The Potential Side Effects of Smoking High-THC Strains

July 12, 2017

Tetrahydrocannabinol, or THC, is the cannabinoid that produces the high feeling that many people love. The side effects that you may experience from THC will vary. In general, the effects are more intense if you consume a strain that has a high concentration of THC. Here are some of the side effects that you may experience after smoking a high-THC strain:


THC activates areas of the brain that are associated with hunger. Because of this, it’s normal to have the munchies after smoking a strain from a Denver dispensary that has a high concentration of THC. Learn about the science of munchies: why does cannabis stimulate your appetite?


High-THC strains can also make you feel tired or lethargic. This is great for people who are smoking marijuana in order to relax or get a good night’s sleep, but if you’re trying to stay focused or be productive, this can be an annoying side effect.


Not everyone who smokes high-THC strains will experience paranoia, but it’s a possibility. The higher the concentration of THC, the more likely it becomes that you will experience some degree of paranoia or anxiety after smoking.

Dry Mouth

THC attaches to cannabinoid receptors in the mouth and decreases the amount of saliva that is produced by your salivary glands. As a result, it’s normal to experience dry mouth after smoking high-THC strains.

Red Eyes

If you plan on smoking a strain that is high in THC, it’s best to keep eye drops handy so you can treat your dry, red eyes. THC causes your blood pressure to lower and the blood vessels in your eyes to dilate, which leads to red eyes. If you’re around other people that don’t know that you smoke, your red eyes could be a dead giveaway that you have recently lit up.

Learning How to Avoid These Negative Side Effects

You may not mind a case of the munchies or a high-THC strain that will help you unwind after work, but no one wants to experience paranoia or dry mouth. How can you enjoy your favorite high-THC strain without experiencing the negative side effects? It helps to start with a low dose and work your way up to ensure you don’t take in too much THC at once. Take a few inhales and then wait to see how the THC affects you before smoking again. In low doses, THC won’t cause the unappealing side effects, so by taking it slow, you could completely avoid paranoia, dry mouth, and extreme drowsiness.

Another option would be to find a strain that also contains a significant amount of CBD, which is another cannabinoid. CBD can counteract the effects of THC, so if you find a strain that has equal amounts of both of these cannabinoids, you may have a more pleasant experience.
