1. What does THC mean?

thc structure


THC is short for tetrahydrocannabinol and is one of the numerous cannabinoids present in cannabis. Alongside CBD, THC is easily the most active and abundant cannabinoid in a large percentage of cannabis strains.

Having been studied extensively, it has been found that THC interacts with the endocannabinoid receptors in the body (located in the brain and various part of the body) to stimulate the secretion of certain chemicals which then lead to the high you get from your weed.

In line with that, it can be inferred that the higher the THC content in the strain you are consuming, the higher you are bound to get too.


2.  Where can I buy THC e-liquid?


Before you set out to buy THC e-liquid or any other related products, make sure the product is legalized in your region. If so, you will be able to get it from a ton of online stores. You can also find out from your local medical marijuana dispensary if they are carrying e-liquids.

We recommend buying online due to the level of anonymity and convenience that it brings. Again ensure you are not buying an adulterated THC.


3.  How can I determine the THC content in edibles?


All you need is a calculator and a basic knowledge of mathematics and numbers. With that, you can head over to watch the video we have embedded below to get your THC content values



4. What is the difference between THCA and THC?




THCA – short for Tetrahydrocannabinolic Acid – has always been reported as closely related to THC. Thanks to solid research, a difference has been established between the duo.

When a cannabis plant is growing, it usually starts with the production of THCA (acidic form) and not THC.

THCA is a non-intoxicating compound that only changes to the THC after exposure to heat over a long period of time. Thus, the THCA allows you to eat the raw cannabis plant without giving you the associated high.

By chance, you might have come across this substance (usually listed as ‘raw cannabis’) in different food products. The interesting thing is that the food products are everyday items that everyone takes. From there, you can already infer that THCA will not get you high while it is still in the acidic form.


5.  How can I mask THC in my urine?


THC is a fat-soluble cannabinoid which means that it is not as easy to get rid of in the body system. In fact, THC can stay in the body for up to 30 days after the last consumption.

If you are having a drug test coming up soon, you will be better off masking the cannabinoid than trying to remove THC completely from your system. Here’s how:


The first thing to do is dilute your metabolites by getting hyper-saturated with water. The amount of water you will need to take will be dependent on your body metabolism.

One thing you should note with this method is that a reputable lab will also test the creatine levels of your urine. This will show if a lot of nutrients have been leached by dilution.

You can game the system by consuming a lot of red meat about 3 days prior to the test.

That will keep your creatine levels up and make sure your urine shows no signs of dilution

Likewise, dilution will usually make your urine appear clearer than normal. In most cases, this is enough basis to have the urine rejected for another sample. To be on the safer side, consume about 50 – 100 milligrams of Vitamin B2 or B12.

Vitamin C is also a good option to add colour to your urine.

If the vitamins you will be consuming are time-release capsules, consider crushing them and ingesting in form of ground pills/ powder to boost their activity in your body. We wouldn’t worry much about clear urine though since people commonly have such without even consuming a lot of fluids.

That being said, you should not start downing large volumes of water days before the test.

That will just amount to a lot of discomforts. Taking about 6 – 8 hefty glasses of water just before the test though will yield desired results.



It is largely untrue that vinegar masks the effects of drugs in your urine. However, it is not so useless to us as it lowers the blood pH levels. This would be very necessary if you have combined a substance like amphetamine with your cannabis.

Acidifying the urine with vinegar will speed up the excretion time of this substance up to 3 times faster.



When you eat foods rich in fibre, your body will work to direct the THC content in the fats to your colon rather than your bladder. That effectively puts a larger percentage of the THC in your stool rather than your urine.

Be careful with fibre supplements though so it doesn’t alter your bowel movements and lead you to dependency



When you exercise, you are also burning a considerable amount of fat. Since the THC is stored in your fat cells, that means you are expelling a good amount into your bloodstream faster. That also means the chances of the THC getting out of your body faster is higher.

It is recommended that you stop exercising a week before the test while keeping to the rest of the practices on this sheet.

That way, you don’t risk releasing more THC into your bloodstream which makes it readily available in your urine

Giving Urine

As a rule, don’t give the first urine of the day in a drug test. The first urine is usually the dirtiest and most concentrated of all you’ll expel during the day. You will have a higher number of metabolites in that urine and stand a lesser chance of avoiding detection.

Another thing is that you don’t direct all of your urine into the cup. Give at the middle stream – start peeing in the toilet, stop quickly and pee in the cup then finish up in the toilet.


6. What is the maximum THC level?


Some marijuana strains have very high THC levels associated with them and will challenge even the most experienced user.

Some of such strains are the hybrid Girls Scout Cookies, Kosher Kush, Ghost Train Haze, The White and Death Star, all of which rank for THC contents more than 20%.

It is even surprising that some of these strains will reach as high as 25% THC content.

That is not to say the names in the list above are the only strains with reported maximum THC contents though. In fact, there is a myriad of others in a list that houses such options as the White Fire OG, GG4, Chemdawg, Bruce Banner and Ghost OG.


7. What has THC besides weed?


Tetrahydrocannabinol is one of the exclusive cannabinoids in weed. That means you cannot find them as naturally-occurring substances in any other plant and animal medium. Any other substance that has THC in them must have been synthesized with the cannabinoid extract as part of the ingredients. Though there might be other substances that mimic the effects of THC.


8.  How much THC is in the Blue Dream strain?


Depending on the growing conditions of this hybrid strain, you will be able to bench anywhere between 17 – 24% of THC in the blue dream strain.

9.  How long does THC stay in saliva?


Even though the cannabinoid can remain active in other parts of the body system for months, the case is not the same for saliva. The traces of THC would have been gone from your saliva in about 8 to 12 hours after the last session.

Generally, you will be safe to give oral swabs and not fear detection after 24 hours since the last time you took any weed.


10.  How long does THC stay in the system


People that have taken marijuana in the past 30 – 45 days stand a chance of being tested positive for drugs if a urine test is conducted. Within 60 – 75 days, it would still be possible to detect amounts of THC in the blood and the THC levels in the hair can stay at a moderate to high level for a period of 90 days, if not more.


11. How long does THC stay in breastmilk after smoking?


It is advised that nursing mothers refrain from taking cannabis (especially by smoking). The THC in marijuana can stay in their bloodstream for four to six weeks. It is a longer timeframe for chronic users since the THC is a fat-soluble substance which would be released into the bloodstream over time.

Consequently, the concentration of THC found in the breast milk is always eight times higher than the one in the blood. This means the baby is not only at risk of getting the psychoactive ingredient but getting more than what you have ever consumed.


12.  What is THC classified as?


There are three main classes of a drug – depressants, hallucinogen and narcotics. The interesting thing about cannabis is that it can function as any one of the three classes due to the cannabinoids present.

Even though CBD acts as the biggest depressant agent in cannabis, the role of THC in all of that cannot be overlooked. Likewise, it needs no telling that some strains of high-THC weed will result in high heart rate, increased blood pressure and rapid breathing in the user.

In such cases, we say the drug is acting like a stimulant.

When use has been prolonged during one session, it is not uncommon for users to report seeing mental images and illusions. At this stage, the same substance has crossed over into the hallucinogen category.


13.  How can I infuse butter with THC?


Butter is yet another substance that you can have your THC infused in, and you can do it at home. Follow the instructions in the video below in other to get it done.



14.  At what temperature does THCA convert to THC?


The non-intoxicating acid component of cannabis will start changing to form THC at about 220 – 222 degrees Fahrenheit. This reaction is referred to as the decarboxylation of THCA to THC and it would be kickstarted about 40 – 45 minutes after the THCA has been exposed to temperature levels suggested above.

To preserve the terpenes, some growers prefer to perform this decarboxylation at lower temperatures. Consequently, that will result in the requirement of a longer time period if the full conversion is to take place.


15.  What is the best way to store THC wax?


This will be dependent on the type of concentrate and its consistency. The following are the most recommended modes of storage for different concentrates

  • Silicone Jar – Make sure the silicone in use is of a medical grade and it would work well for just about any type of wax you want to store. The material makes it easy to get all of your wax out when you need it. However, you should not use a single container for more than a week due to the fact that silicone is not so air-tight


  • Parchment paper – They are ideal for storing shatter. Cut up just enough to cover up the wax and keep it from external elements. It can be used both short term and long term too.


For short-term usage, all you need do is make sure the parchment is kept in a cool, dark place. Long-term storage needs will require that you put the parchment paper in another container that will better protect the contents from external conditions


  • Glass jars – Glass jars should be used selectively since some wax dabs are known to stick to the sides. Therefore, you will have better luck using a glass jar to store such concentrates as crumble, sauce, sugars and others that are not known to stick to glass ever so tightly.


  • Plastic Jars – Only consider plastic container when your storage needs are short term. Again, don’t store anything that will be aggressively stick inside the plastic


16.  How much of THC is in hemp seeds?


Hemp seeds contain about 0.3 per cent or less of THC. That is surely not enough to be of a major concern to you if you don’t want any of the psychoactive effects to manifest in you.

17.  How can I buy THC oil online?


There is no science to the purchase of THC oil from online stores.

Before you place the order, make sure the product is supported by the law in your area so you don’t find yourself in an unpleasant situation. It is a good practice to look out for stores with good reviews on the internet.

After that, check one that is likely in your area/ offers faster delivery to your area. Given the fact that there are a lot of these stores out there, you will find what you are looking for quite fast enough.


18.  How can I make THC dab?


Dabs are usually referred to as concentrates. To make and enjoy your own concentrates, the video embedded below will show you how to make your THC dab (concentrates).

Please do not attempt to make these by yourself if you are not sure you have gotten the full hang of it. Dabs are highly-concentrated forms of your regular cannabis and you don’t want to go wrong with them. They are usually potent (contain high THC).




19.  What is the percentage of THC in weed?


The amount of THC in weed varies largely from strain to strain. While they hide under the general canopy of the name ‘weed,’ these strains have wildly different features.

That is why you can get as low as a 0.4% THC content in strains such as ACDC and as high as 25% of the same cannabinoid in other strains like the Girls Scout Cookies.


20.  How is the percentage of THC measured?


You can measure the amount of THC in your marijuana at home by following the steps laid out in the video embedded below.



21 How do I pass a hair follicle test for THC?


THC can stay in your system for a while but when it comes to hair tests, the story takes a new dynamic. In fact, the THC can stay in your hair for up to a year until the hair falls off or is shaved.

However, all hope is not lost. If you have a hair follicle test coming up, take the following into consideration.

  • If you have not been smoking weed in the last 90 days, you are in the clear. Thus, if you have been advanced on a drug test, you should refrain from smoking weed in that timeframe.


  • If you have only been smoking weed sparingly in the last 90 days, you run a lesser risk of triggering a positive result on that test


  • If you have just recently smoked weed, you don’t need to fear getting caught on the test. Hair ‘contaminated’ with the weed will need an average of 5 – 10 days to break onto the surface and you would have long left the test venue before then

While noting things to do, there are some things you should not attempt either:

  • The first of these is shaving the hair on your head. The menfolk would be more prone to taking such a decision. What you don’t know is that the testers could take hair from any other part of your body. Since these are slow-growing hairs, your chances of passing that test become slimmer


  • You should also refrain from dyeing the hair. In the end, the labs are not interested in checking for the ‘smell’ of weed in your hair. They are instead concerned about the weed metabolites in there.


From research, dyes would do nothing to interact with those metabolites.


  • Some have also tried to use hair extensions to trick lab technicians to take a sample of THC-free hair that isn’t theirs. While this might work, these technicians have been specially trained to look out for such things. You wouldn’t want to come out holding the shorter end of that stick.


22.  How much THC is in BHO?


BHO stands for ‘butane hash oil’ and is one of the THC concentrates on the market. Being in that group means it can contain extremely high levels of THC which can be anywhere from 40% to as high as 80%.


23. How fast does THC degrade?


The rate at which the THC content of your weed will suffer degradation will be dependent on a handful of factors. Every one of these factors can be taken and lumped under the storage conditions you subject your cannabis to.

The amount of exposure to direct UV rays, humidity and ambient oxygen levels will determine how fast the weed will lose its value in terms of THC content.

Likewise, continued exposure to temperatures beyond 70 degrees Fahrenheit will start favouring the build of moulds and bacterial growth within the flowers.


24. What are THC pills for?


THC pills are, as their name suggests, pills that have been made with a decent concentration of THC in them. Perhaps the biggest advantage that THC pills bring on board is the safe mode of consumption it allows users.

Even though smoking cannabis is not as dangerous to the health as smoking tobacco, it still manages to raise a couple of concerns.

However, you should note that a major drawback of edibles is also present in these pills. They take a long time to kick in and that can seriously affect how different users dose them. Besides that, they pose a great alternative to smoking – especially for those averse to smoking anything in the first place.

25.  What does THC help with?


The vast majority of people that know THC are only aware of the effects of euphoria and high that it brings with it. Fortunately, this cannabinoid functions in so much more categories.

It has been found out to have some effects on the inhibition of tumour growths in cancer patients, improvement of appetite, help with nausea, alleviation of pain and prevention of seizures.

The same cannabinoid has even more applications in the promotion of sleep, brain improvement and insulin sensitivity.


26.  How much of THC is present in the Sour Diesel Strain?


Sour Diesel can be lumped up there with the list of medium to highly potent marijuana strains. During tests, the strain can record a maximum low of 19% and go as high as 25% for THC.

27. How can I make pot brownies with THC oil?


Enjoy your THC edibles in form of brownies by looking at the recipe provided in the video below



28.  How long will THC edibles last?


THC edibles are not only notorious for taking a while before they kick in. They are also popular for giving you a more potent and longer high than smoking. After they kick in, you can expect the edibles to last for anywhere between 4 – 8 hours.

The wide variation in time is due to different reasons. For one, the strain you are consuming will play a crucial role as evident from its THC content. Likewise, the amount of the THC is equally important as well as your own body.


29.  How was THC discovered?


There is a solid background story to the discovery of THC. This story follows that the cannabinoid was first extracted in an Israeli lab by a team of scientists led by a Dr Raphael Mecholaum.

His extraction and singling out of the cannabinoid in the year 1964 was also believed to have set the pace for extensive research into the substance, especially as it can be applied to the medical cannabis context.

What this story does not take into consideration is some pieces of literature which suggest the presence and use of the cannabinoid way before this time. If that path is towed, one would be met with the shocking revelation of an uncelebrated individual who first made the discovery.

Going by the name of Roger Adams, perhaps the reason why this man never got the credit for his work was that he never trained as a scientist.

Whoever you choose to credit for the discovery though, we are no less thankful for their work.


30.  How can I make THC concentrate oil?


You can make your THC concentrate oil yourself by following the instructions provided in the video embedded below



31. Where is THC stored in your body?


THC is only soluble in fat and so are stored in the fat cells of the body. That choice location of storage helps them stay longer in the body system, releasing into the bloodstream with the breakdown of fat molecules in the body.


32.  What is the required amount of THC to pass a drug test?


To come out with a negative result on a blood test for marijuana (THC metabolites), the lab will need to have found 50ng/mL or less of the substance in your body. However, some labs can take their pass point to as low as 25ng/mL


33.  How can I use a THC vape pen?


The first thing is to obtain the desired weed strain with the amount of THC you want to consume and also, a vape pen to match. If this is your first time with the pen. Follow the steps below:

Plug the vape pen:

Vape pens are notorious for needing a high amount of energy to operate. In line with that, it is also disappointing that quite a lot of them will take long hours to charge up. Since it is recommended that you get those lithium-ion batteries high before you get your own high, you might want to get started on charging the pen early.


Read the manual:

This might sound generic but a lot of users fail to read the manual until the pen develops a fault. That booklet is not just in the pack to make our product look fancier.

The manufacturer will usually include some details as to optimal operational conditions, ideal storage practices and so on.

This information will help you get the best out of the vape pen and make it serve you for longer.

Take a dry run:

When you have gotten sufficient charge on the pen, consider dry-running it. Put the pen on while not putting in any herb or oil. That will help get rid of manufacturing materials that might be loitering in the pen chamber which could have entered your lungs while vaping.

Load the chamber:

Now that we have gotten every other thing out of the way, it is time to load up the chamber. Unmixed oils will usually be dabbed directly onto the atomizer in small amounts to get the vaping started.

If you will be using dry flowers instead, they should go into the chamber in a ground form. They are then made to sit on top of the atomizer or go into a metal chamber from where they are heated up.

Get A-toking:

Some vape pens are built to heat up when you inhale while others will require the manual push of a button. Whichever way it is, you will get a light to signal that the machine is up and running. Take the mouthpiece in your mouth and pull in some of that vapour.

It is best to take slow, gentle puffs than try to take large ones. You have a better chance of getting a much better high doing the former than the latter.

34. What are THC tinctures?


THC tinctures are medicine made from cannabis which requires dissolving of the plant in alcohol. The aim of the alcohol is to extract the terpenes and other important cannabinoids (such as THC) from the plant.

For this to work, full decarboxylation must have occurred in the cannabis plant. Else, the medicine won’t be as strong as it should be.

Just like edibles, tinctures are made to be consumed orally. They can also be used sublingually and even put into any type of food. Used alone, they kick in faster than edibles.


35. What are THC concentrates?

thc concentrate


THC concentrates are cannabis products which have been specially made to have a very high amount of the cannabinoid in them. While that definition is general enough, there are different types of concentrates to consider on the market today.

Some of those are:

  • Kief – This is the first widely-known substance to be dubbed a concentrate. Kiefs are used to refer to pure trichome heads. On applying heat and pressure to Kiefs, you get what is known aS.


  • Hash – Containing compressed resin glands, hash provides an even better way of consuming cannabis with the focus on THC content


  • Tinctures – This general term is applied to a series of cannabis oils concentrated to have high amounts of THC in them. They can either be consumed sublingually or by smoking


  • Butane Hash Oil – Referred to as BHO for short, they remain one of the most common forms of concentrated THC in oil form. Besides high THC, BHO is also highly rich in terpenes and cannabinoids


  • Distillate – Distillates take on a more scientific approach, converting crude oils into highly-concentrated THC substances through the (obviously) distillation process.


  • Rosin – Much like kief and hash, Rosin is yet another way to obtain THC concentrates without the need for an extracting solvent.


There are a couple more concentrates you might come across but the above are the most common ones around.


36. Can I take THC-cannabis when I’m sick?


This depends on what you are sick with. If you have the flu, lung or respiratory problems, it is not advisable that you continue with smoking weed for the high. You will be contributing to the problem rather than solving it. If you must get high, consider edibles and tinctures instead.

For any other type of sickness though, you should be fine with going on with weed – if you must.

Although there has been no extensive research in the field, there is a theoretical belief that THC in weed will lead to an impedance of the immune system.

Put clearly, THC might affect the rate at which your immune system is able to fight off the infection from what you are sick with.

Of course, all that is just theoretical. Even if it wasn’t, the effects of the THC on your immune system should not be a cause for concern.


37. What is THC soluble in?



The cannabinoid has been widely researched and reported as a fat-soluble compound. Thus, its natural affinity to bind to/ get stored in the human body’s fat cells


38. What is the best temperature to vape THC?


There are different temperatures for vaping weed but only a select range will give you the cerebral or body high that is often associated with THC.

That being said, you will want to set your vaping machine to about 185ºC. You can take this up to 190 ºC but not more. Going above that threshold will induce a more bodily high (CBD release) than cerebral effects.


39.  How can I make THC shatter?


We have sourced a video for you (embedded below) that will take you through the steps of making THC-infused shatter at home. Enjoy!



40. What receptors does THC bind to?


There are two main cannabinoid receptors in the human body – CB1 and CB2. THC binds to the CB1 receptor which is largely in the brain but is also present in the lungs, liver, lungs, fat, uterus and even sperm cell walls.



Those are the 40 most common questions about THC as well as additional resources to help you better. If you’ve got something to share or an inquiry to make, we will be looking forward to hearing from you in the comments section.
