Same with me, I stopped MANY years ago. Don't you remember everyone just sitting around, spaced out? The laughing jags? But from what I hear, mj has gotten much more powerful in its affects these days. Plus is mj even popular anymore? Don't even know if there is still a market out there for it? I think "designer" drugs are more popular now. Now that is scarey stuff!
I know it used to cost $20 per oz. when I smoked it but now the price has skyrocketed. I see on some threads they mention over $400 per oz. Ouch!
I remember laughing like crazy the first few times I smoked it but after that hardly at all. But the first few times I couldn't stop laughing.
As for the stength, we used to get some pretty powerful stuff from Columbia, Panama, Thailand, Vietnam, etc. Soldiers would bring it home with them, and sailors too. I can't see the stuff today being any more powerful than what we used to get. And I guess low-grade Mexican is still low-grade Mexican.
I have no idea how popular it is anymore. I wonder that myself.
But I'm sure that there will always be a market for it. Just by being illegal it makes certain people have to try it.
