Really?I don't.Strains that are really high in THC and low in CBD make my heart race and make me anxious. IF I smoke them before bed I end up staying awake all night. Strains like Trainwreck, Silver Haze and Durban.When it has some CBD in it, I like it way way way better. It takes away anxiety, doesn't give me heart palpatations, and it doesn't make me worry about shit. Strains like Cookies, OG and ChemdawgStrain like Girl Scout Cookies is 20%+ THC, but also has 5% CBD. Same with a lot of OG's - high THC, but balanced with alot of CBDI've actually convulsed from taking too much THC that didn't have any CBD in it. Funny thing is I really didn't feel all that high, just uncomfortable, and then all of a sudden I started seizing.Personally, I think CBD is the medicine and THC is the recreational drug.
