How Much THC is in a Bowl, Dab, and a Joint? [Finally Answered]

When you smoke weed, it is wise to know how much THC – the psychoactive compound in cannabis – you are consuming at any one time. There are a multitude of ways to use cannabis, and although smoking a joint is the ‘traditional’ method, an increasing number of people are dabbing. You also have the option of increasing the amount of THC you use by utilizing bowls.

However, measuring the amount you consume is very difficult. What you get from a joint is NOT the same as what you consume via dabs, for example. And of course, the type of strain also dictates consumption levels.

In this guide, we attempt to make things a little easier by outlining the approximate amount of THC in a bowl, a dab, and a standard joint. Before we begin, though, it is important to note that the method you use has a major impact on how much THC gets into your system. Other factors to consider include a person’s lung capacity, weight, size, overall health, and even their personal preference on how they inhale.

How Many Mg of THC in a Dab? We Have the Answer

Overall, those who dab THC will receive a higher amount of the cannabinoid because they are dabbing concentrates. It is normal for a concentrate such as wax or shatter to contain at least 70% THC, and the highest THC dabs on the market contain over 90%! Bear in mind that only a few strains you’ll smoke in a joint contain more than 25% THC.

On the downside, it isn’t easy to calculate the amount of wax you use each time you dab, so it may be worth investing in an accurate weighing scale. Let’s say you use 30mg of a dab which has a THC content of 70%. The wax has 21 mg of THC, but you could lose up to one-third of it when vaporizing. If this happens, you’ll end up with 14 mg of THC per hit.

Again, respect the potency of the dab! Imagine purchasing a smokable marijuana strain with 18% THC. 1 gram would equate to 180mg of THC. If you purchase a 90% THC dab, you only need 200mg to achieve the same level of consumption of the psychoactive compound.

Moreover, as you take in more of it per hit, the effect is magnified; if you consume 180mg of THC quickly, you will quickly regret that decision — trust us.

How Many Mg of THC in a Bowl?

The mg of THC in a bowl really depends on how tightly you pack it, along with the maximum capacity of the bowl you choose. Once again, we have to make a few assumptions to provide you with a decent overview of the amount of mg of THC in a marijuana bowl. For instance, it is normal for a bowl to contain 0.25 grams of weed.

So let’s say you purchased decent quality weed with a THC content of 18%. Remember, one gram of weed equates to roughly 180mg THC. Some experts believe that you will lose up to 60% during combustion (more on that later), but had there been no loss whatsoever, you would have 45 mg of THC in your bowl. As you only consumed only 40% of that amount due to burning, though, your bowl likely has around 18mg of actual THC.

How Much THC is in a Joint?

When it comes to calculating how many mg of THC there are in a joint, you encounter the same issues as you do with dabs and bowls. You need to consider the strength of the weed, the loss of THC due to combustion, and the size of the joint you roll, among other factors. If you only lost half of the THC due to burning, a gram of 18% THC weed would enable you to consume 90mg of THC.

To be honest, the above is a little bit simplistic, but we felt it necessary to provide an easy-to-digest overview of THC consumption. According to a study published on the UK Cannabis Internet Activists website in 1990, anywhere between 40% and 50% of THC is lost when smoking joints – less than when you use a bowl, but more than when you dab.

Therefore, a marijuana strain with 20% THC offers 200mg per gram, but you will inhale a maximum of 120mg (assuming you ‘only’ lose 40%). There is also a major difference in how much weed is contained in an average joint. Christopher Ingraham of The Washington Post suggested that a joint contains 0.32 grams of marijuana, and this analysis was published in Drug and Alcohol Dependence in 2016.

As a result, we can multiply 0.32 by 120 mg to end up with 38.4mg of THC per joint in a best-case scenario. However, it has also been suggested that 0.75 grams is a popular joint size. In this case, each large joint would have a whopping 90 mg of THC once you have accounted for combustion losses.

All of this may not seem too complicated, but we’re not done yet! When your joint is burning, THC condenses towards its end, which means the first half of your joint is less potent than the second half. In other words, half #1 may have 40 mg, while half #2 has 50mg.

Final Thoughts on Bowl vs Joint vs Dab THC Content

Overall, dabbing provides you with the most THC per gram, but it is far more expensive than dry herb. The enormous amount of THC contained in dabs means that it is ultra-potent, and is not suitable for beginners. Dab rigs are designed with this potency in mind, which means you use far less wax than dry herb.

We discovered that regardless of whether you are a smoker, dabber, or vaper, the amount of THC you consume per session doesn’t vary a great deal. In fact, you can expect to inhale around 15mg to 35mg of THC every time. What this THC consumption does to you depends entirely on your particular tolerance level. Always begin with the smallest possible amount, and work your way up accordingly.

We have not even discussed the act of vaporizing dry herb, which could provide an increase in THC of up to 20% when compared to smoking a joint! You can vaporize dry herb or dabs; the latter is vaped the vast majority of the time, although some users like to sprinkle some wax into their joints or bowls for an extra THC-laden boost!
