Ok alot of people will disagree with me and I was even on the other side at one point. But try holding your hits in longer, I swear you get higher that way lol. Anyways maybe your body is just fairly new to THC, shit I dunno why you didnt get that stoned but I pretty am damn stonoed lol. People who say it doesnt matter how long you hold it in is probably smokin some bomb dog diggity lol.
