Done weed only. It started in Amsterdam with a brownie. Never laughed that much in my life. But later experiences were less about laughing and more of a woozy experience. I once spent a day in Amsterdam going from coffee shops to coffee shops smoking joints and eating brownies. What a day... (It was Queen's Day in Amsterdam. Literally the whole city was in the streets in orange, celebrating)
The after taste the next morning was fucked up though. Would say that was pretty much the only negative. However, I did go into a dark zone after drinking quite a bit and smoking one joint. But it got better later on. I blame the alcohol more for that honestly. Alcohol can really get to me sometimes, as opposite to weed. I'd rather overdose on weed than alcohol anytime!
Miss weed like hell now, it's too hard to get it now where I live.
