A little while ago I got some weed and it looked ok and it smelled ok but when I vaporised it out of my volcano I couldn't taste what I smelled and instead got a weird chemically taste. The weed got me pretty high but the next day I had a headache and my body just felt really weird (long term smoke and vape user and I've never felt anything like this before no matter how heavy the sessions were.) It left my easy valve filling chamber smelling a bit odd too. My guy took it back and gave me some other stuff that looked good and smelled good. I completely stripped my volcano filling chambers with pure ISO and got a new bag etc. When I vaped it I got a good taste and a good high but the next day I experienced this same headache and weird body feeling. These symptoms are bad the morning after and I still feel groggy two days later and I noticed that my filling chamber has the same odd smell about it now even though I could only taste the bud when I was vaping. My guy has been smoking this stuff and he says that he hasn't noticed any of the symptoms I am talking about (although he believes what I say as we have known each other a long time) What could possibly be in the weed that is causing this? Could it be something that is destroyed by smoking but becomes vapour at lower temperatures? Has anyone else had similar experiences? How dangerous could it be? My guy said he will swap it for me the next time he gets something else in but I don't want to have to be deep cleaning my gear every time I pick up! Any help or ideas would be greatly appreciated.
