Let me simply start out by saying I do not care what other people do, but I believe a big goal of this site is considered Harm Reduction! I'm not your dad, I have no authority in your life and can't tell you what to do. But the simple answer is YES! My advice would be to stop smoking spice IMMEDIATELY! I smoked about a gram to a gram and a half daily for 18 months on probation. Then one morning I waked and baked with some spice. I experienced the worst sensations in my body ever - feeling like I was having a heart attack and I was literally going to die. Later I found out this was a simple panic attack. However, ever since that awful morning in June I can't even smoke regular marijuana without having a panic attack. My anxiety is now to the point where drugs don't even trigger it anymore. If I don't have any benzos around I will literally freak the fuck out. I would stop before you do serious damage to your body. This isn't something that happens over time like cirrhosis with liquor. It can happen so easily you'll never know when it was too late. Spice is poison, and in my opinion the worst synthetic drug in the world. The one good thing the DEA has ever done was getting rid of it from the shelves. Unfortunately, there are still shops that sell it with even more unknown possibly harmful chemicals. Did you not read about the story of the 14 year old girl in Texas who lost all her brain function and became paralyzed because of that shit? She was smoking just as much as you and I were.
Proceed with caution my friend.
