I just found out about Delta-8 and 10 THC. What exactly are they and why are they legal where normal weed isn't?
EDIT:
Just for anyone else who finds this thread, wondering about Delta-8 and Delta-10 THC. This is what I've found. Take it with a grain of salt.
What I've found all seems to roughly agree with each other. Neither has the same psychedelic effects of Delta-9 (traditional marijuana). Delta 8 is a more a calming body high somewhat resembling Indica strains of marijuana so it's good for nigh time use and sleep. Delta 10 is more like Sativa so it's more uplifting, energetic and creative, good for daytime and focus. 10 is not more potent than 8 and neither are as potent as 9. And even in high doses, neither 8 or 10 give the same, psychedelic, out of your body, drug trip type of experience that you get from traditional marijuana. Delta-10 also seems to be harder (if not impossible) to find on it's own but is available mixed with Delta-8
