All that genuinely matters in determining how a strain will make you believe is the combination of terpenes & cannabinoids.
If you have spent any time researching cannabis, you have likely come across the classifications of sativa & indica… There are many myths surrounding these distinctions, like that one has more THC than others, or that all indica will give you a body high, while sativas give more of a head high, however these distinctions aren’t as black & pale white as many people will tell you. To be honest, with the way that cannabis cultivation has trended in the past few years, you will be tough pressed to find one strain that is all indica or all sativa, most cannabis strains available nowadays are a hybrid, or a combination of the multiple. All that genuinely matters in determining how a strain will make you believe is the combination of terpenes & cannabinoids. Cannabinoids bind to receptors in our brain that make us believe the unusual effects of cannabis. There are over a hundred unusual cannabinoids identified in the cannabis plant, the most popular of which are THC & CBD, however indica strains are known to have higher levels of the cannabinoid myrcene, which can contribute to more of a body-high feeling sometimes. The reason that sativa cannabis strains have a reputation for being more of a euphoric, heady high isn’t well known, however it may simply be for the fact that sativas have a lower level of myrcene, which makes them tend to have less of a body high feeling. The best way to determine the best cannabis strains for you is to go to your local dispensary & speak with the budtender about the effect you’re trying to achieve, & they can suggest the best cannabis strain for you!
