Every marijuana smoker knows about THC. It’s the main psychoactive cannabinoid in the marijuana plant that many are looking for.  The main thing smokers, vapers, and dabbers enjoy about high THC strains is those mind-blowing highs. High THC strains can have you sitting on the couch lost in your own mind-bending thoughts. Or can have you giggling uncontrollably as you and your friends come up with high ideas. It all depends on the strains you use.

For those growing strains high in THC from marijuana seeds, they can also contribute to high resin production. This can be great for those that want to make hash, or just enjoy the super frosty look of their buds as they grow.

THC formula, Tetrahydrocannabinol

A strain high in THC can also be beneficial for medicinal users. Sometimes conditions can be so bad that medicinal patients find they have to use a lot of marijuana. Hitting the bowl or joint several times in a very short space of time isn't always a good thing. It can contribute to some unhealthy side effects, such as damaging the lungs.  High THC strains can help with this, as fewer tokes will need to be taken, but patients will still get the relief they need.

So, now that the benefits of high THC strains are understood, what strains are best when one is looking for high amounts of THC?  For both medicinal and recreational use, these are the top ten strains high in THC in 2021.
