I was riding the bus a while back and these two people were talking in the seat in front of me about something very similar. This one mentioned that he hadn't tried any kind of weed
for literally decades, so he got some of the legal stuff from a website that had lab reports that indicated no banned substances were being used- the bus went over a bump and I didn't hear the brand.
Anyway, he said he took about a quarter teaspoon of the stuff, enough to fill a pipe and took about 10-12 hits. (I guess back in the hippy times that was the way it was done.) At any rate, he said he felt like someone had put a fishbowl over his head and he got super confused-- like he couldn't remember the next thing he wanted to do or why. He started to panic, because he was so stoned and it was a different feeling than he had ever had before. Once he stopped feeling overwhelmed, he said it was like he was having a conversation with Jesus, who was helping him be calm, and who let him talk with his father, who had passed away about a year ago.
That calmed him down a lot, talking with his father, who was reassuring him. Then he started to sort of meditate, much calmer, and all of a sudden said he recalled some long ago memories and feelings like he was re-living them: when he was first married, and how much his wife meant to him (they apparently hadn't been getting along). Once he saw he could function, he started to have a pretty good time of it, but he also experienced things like numbness in his body, which was actually welcome because he had various aches and pains. Also, the experience made him better in some ways, he saw what was important to him, and realized he'd made a mistake in underestimating this stuff he smoked.
After hearing that I don't know that I'd have the nerve to try it. Pretty much a wuss, you won't see me providing any "swim
trip reports"-- I'm more into 100% natural, ethnobotanicals
done in traditional ways.
