THC and CBD are cannabinoids, which are naturally occurring compounds found in the bud you smoke. There are a lot more cannabinoids found in green, but these two are the most commonly known.
So what are they, and what makes them so popular?
Tetrahydrocannabinol - also known as 'THC' - to put simply, is what makes you feel high when you smoke.
Yup, that all too familiar feeling you get after a quick puff-puff-pass (you know, the one that makes your head feel hit with a happy brick?) is predominantly thanks to our little friend THC, which probably explains a little already as to why the compound is so damn famous.
It's pretty simple - the more THC you ingest, the stronger the high and stronger the effects you'll feel. For advanced smokers looking for a potent hit, a THC Dominant strain is ideal.
That being said, more effects can mean heightened risk of experiencing other effects, such as anxiety.
Cannabidiol, more commonly referred to as 'CBD' has rapidly gained popularity in recent years thanks to its therapeutic properties that, if ingested without THC, come without the psychoactive effects listed above.
For individuals who aren't looking to get high when they smoke - or aren't even looking to smoke at all - they can source CBD in a variety of available forms to help with things like anxiety and paranoia, and it's even been known to dramatically decrease the side effects of a number of mental health conditions.
So, how does this help you?
Once you understand these two main cannabinoids you're going to find in your bud, you can start making decisions on how you want to access them.
You can find a number of balanced THC-CBD strains, and these are often the more popular choices for recreational smokers.
We're all different, and have different tolerance levels. If you're a new smoker it's better to start with a strain that has weaker THC levels and work your way up.
It's always best to get advice from your budtender based on what you're looking for, and any concerns you have about different side effects.
