My strongest one was datura stramonii. I got myself an extract from the pharmacy, so I could measure it accurately. I drank 100ml of the extract, containing 30mg of the compounds (atropine and scopolamine). Unfortunately I let out of view, that the extract contained 93% ethanol (which meant, that I drank the same amount of alcohol than in 2 liters of beer). It was the only trip in my life, that had to be stopped by my sitter (after 7 hours), because I started demolishing the whole apartment. My sitter had to call help, because she couldn´t stop me alone (I always have some friends in the backhand when doing really heavy stuff). It took 5 men (!) to hold me and inject the antitoxine (neostigmin). Also they had to give me 120mgs (!) of valium to get me down (fortunately, one of the friends that came for help was a pharmacist, who knew very much about natural drugs). I still had some hallus for another 3 days, but I could handle them.
I asked for it. But I´m a physician, so I´m allowed to buy that stuff. Datura extract is still manufactured, because it´s used for homoeopathic mixtures.
Yes and No! I found it quite interesting, but my sitter didn´t! I´ll maybe do it again one day, but with better preparation and maybe only 20mg. And only with the ethanol removed from the mixture.
Personally the only legal psychoactive drugs I've done are: hawaiian baby woodrose seeds, morning glories, mushrooms (fresh, psilocybin ..aren't they only illegal in Florida if their dried?), dxm, and salvia. Salvia is mind blowing, but its rediculous how much money I wasted just trying to figure out how to get off on it. Hawaiian baby woodrose seeds I had taken one afternoon and they fucked me up but I wouldn't consider the experience a trip. Morning glories.. very fun, but disgusting. However PERFECT with shrooms. A very good trip enhancer. DXM, interesting, it was a very insightful experience.. but fairly irrational (I figured out what love was...) and I don't like the potential long term side affects so I wouldnt do it again. I did it a lot when I was younger. Mushrooms.. they're the best, well besides L.. but thats not legal unfortunatly.
One hit of 10x standardized salvia extract turned my world into neon-lined rubber for 5 minutes. Sweet jesus it's powerful stuff.
I have tripped hardest on 2c-i and 2c-e. i tripped really fucking hard on salvia but it dosent seem to stick in my mind when i think of my hardest trips. DXM- meh, i just dont see what all the excitement is about, HBW seeds- i took about 10 will little affect, i think it was because of my meds at the time, but i know people who have tripped really fucking hard off it.
salvia is the most intense drug ive ever done, but the thing is it only lasts for such a short time... but i was in another dimension.
