I agree with everything you said there and I was saying the above to my missus last night. I also said, just because the Buddha didn't enjoy the ganj, doesn't mean it's not sacred. It's very important to me that the plant is respected at all times. I've felt like that since my first experiences with it in the 70's. I've never ripped anyone off or ever sold any mouldy weed etc and if anyone ever rips me off, I get more upset me that they've disrespected the plant, than the fact that I've lost some money.
I agree that it's very difficult to police THC levels. I just think it's a shame that they increased the power of it in the first place because as you say, it's been used for millenia without any problems. Most of my older friends don't want to smoke the newer, stronger strains because it does their heads in. Like you, I used to enjoy the stronger stuff for the buzz but I wouldn't touch it with a bargepole these days.
I've been making my own edibles for years and almost every time I'm making cakes, I end up eating too much by licking the spoon and I've had some very intense and frightening experiences over the years. During one of the worst episodes, I honestly didn't know what life form I was for a while then when I'd calmed down a bit, I couldn't work out which hotel or town or country I was in, then I got very paranoid that I could be robbed at any minute.
I ended up totally naked and pouring with sweat, crouched in the corner of the hotel room and holding a large knife, which I'd been cutting the fudge into squares with. Suddenly the door swung open and the hotel manager said "And we have this room....' saw me crouching there, looking wild eyed and naked with a large knife, then quickly shut the door, saying, 'My mistake. Someone's in that room' ...lmao
I went back there several times over the years but we never talked about that.
