Ever sense I got a new dealer (he's a legal caregiver), I've been having trouble breathing after toke sessions. He said he generally picks up sativa dominant bud. This time I got California Mist. I'm not sure if i've struck gold with the dankest weed i've ever found or if he may be putting something in the MJ? I usually start tripping out around 20 minutes after i'm done smoking and my buzz has already set in, then at random I get really FUCKED UP and cant breath, seems to go on for around half an hour-hr til my high comes down a little. any thoughts on this please and thank you?
