I don't think you get flashbacks from shrooms at all... You get acid flashbacks because even though the drug may seem to wear off it always stays in your body... I think it stays in your spine but I'm not sure about that. I was thinking about trying shrooms but not acid only because it can mess with your chromosomes. If you have kids there is a chance that something will be wrong with them because your chromosomes are messed up.
I prefer to use dealers who only sell weed (Thats pretty much the only drug I do, occasionally i will do others). Dealers that only sell weed tend to be a lot less shady than dealers who have a mini-mart full of stuff. I got weed from a guy that sold just about everything else (even shit i had never heard of before) and he would mist his pot with water to make it heavier. I ended up getting around 3/4 an ounce when buying an ounce from him.
My sponser, neighboor, friend, dealer sells (and smokes me up almost everynight) ganja and mush. Of course it's his brother who can hook up the good deals. If I buy more drugs (such as acid or mescaline) I have to get it from another guy. But I live in Kansas, and our drug supply here is awfuly low. A roll is $25 compared to $3 in Seatlle! -Peace (and Love) .
My fault then. I shouldn't have said it like I knew exactly what I was talking about. I've never done shrooms or acid, so be it myths or whatever it is, these things are just things that I've heard of.
Don't listen to anyone who tells you they are the same. Anyway, I found this thing on Erowid that might help you out. The guy who wrote it is named Ellis. Maybe it is the one from here, who knows...So here it is: 4d. Differences between psychedelic drugs LSD and psilocybin, while similar, are not the same. Here's a nice article by Ellis Dee (an188749@anon.penet.fi) summarizing the differences: "Here's a partial list of differences between the effects of LSD and psilocybin, as I see them (your mileage may vary) --- (key -- P: psilocybin; L: LSD-25) Duration P: onset: 30 minutes; peak 90 minutes; duration: 6 hours L: onset: 60 minutes; peak 2-3 hours; duration: 10 hours Stimulation L: pronounced stimulant effect, similar to phenethylamines P: little stimulant effect, sometimes inducing mild sleepyness Perception scope of effect L: all sense fields -- visual, auditory, tactile, kinesthetic P: primarily visual [Eds: We disagree with this one.] perceptual integration L: profound synesthesia in high doses, especially visual perception of auditory stimuli P: limited synesthesia, even in high doses visual speciificity L: general, wide spectrum of possible effects P: somewhat specific, with recurrent forms aesthetics L: neutral, visuals ranging from the banal to the sublime P: visions of sublime beauty the norm color hue L: primary or spectral colors P: 'earthy' composite warm colors color-object association, mobility L: abstract, colors moving and changing freely P: concrete, colors fused to objects other qualities L: transparent, neutral P: rich, lustrous patterns detail L: fine detail, fractal-like quality P: little emphasis on detail form L: great variety of form; small lines, facets elucidate structure P: broad interlocking regions containing different colors bounded by curved, clean edges consciousness, general ego dissolution L: profound depersonalization accompanying experience of the underlying unity and boundlessness of everything P: mild depersonalization accompanying experience of beauty in and empathy with other beings/phenomena expansiveness L: very expansive, multiplicity of thought and emotion, sense of boundlessness P: mildly expansive cognition and perception L: cognition and perception are intimately associated, perception seeming to be largely directed by cognitive processes P: perception is little affected by cognition continuity L: high degree of continuity imparted (apparently) by the mediation of perception by cognition P: little continuity as one intense sensation replaces another Some of the differences are exaggerated slightly for clarity."
