I'm not "against" it, but I'm not really inspired to do it either. I feel like intact cultures have more room for these things, as they have a guided experience within a culture that is deeply rooted to a place. Transporting these things across time and space, and taking them without the cultural "container" may lead to disastrous results. That said, I know a lot of people who have been positively impacted by taking these plants into their bodies. I enjoyed experiences myself as a teenager. I think they should not be taken lightly, or for "recreation."
I feel like there were a couple articles written about this topic in the old Green Anarchy magazine. They are all archived online now, but I ain't gonna surf through them to find it. Anyone remember which issue?
