As far as the doctors and scientists saw until now, the magic mushrooms have no known adverse side-effects, if we don’t count the fatigueness that you feel after come-down. Anyway we must not forget that magic mushrooms, like any other psychedelic drugs, are powerful mental amplifiers. Don’t even think to use psychedelic drugs generally and magic mushrooms particularly if you have depression, anxiety or life problems in general.

Mushroom effects and your reaction to them are strongly determined by set and setting. Set is your mindset when taking the drug; setting is where you are. The magic mushroom effect makes you enormously sensitive to your environment so you should always be in a safe, comfortable environment, preferably with a friend you trust.
Magic mushroom users can have flashbacks that recreate a trip after it has ended. Being tired or stressed out can trigger a flashback. Difficulty concentrating and memory loss may also occur. Flashbacks days or even months afterwards are often cited as a common side-effect of hallucinogenic drugs. There’s little evidence that these are a given. Anecdotal studies have shown that only about 15% of users report any phenomenon close to a flashback.
Mushrooms are not physically addictive but someone may turn to them repeatedly to escape from their everyday life though. A user may start by taking a small dose and then repeat the process if they don’t feel the effects of the mushrooms within a short time. However, as with any mind-altering substance, users contend their psychological effects can be compelling and therefore hard to resist. As with any drug, beware of doing too much, too frequently and letting it define you. Be careful.
Tolerance builds up rapidly with mushrooms. For 24 hours after a trip you have to take twice as much to repeat the same effect. Tolerance lasts about three to four days. There is also some cross-tolerance with other psychedelic drugs of the tryptamine family (such LSD and DMT) but not Ecstasy or Ketamine.
We strongly recommend to everyone reading this article to stay out of magic mushrooms abuse, however, if you or someone close to you have problems with magic mushrooms addiction, we suggest you to visit Drug Rehabilitation centers in Canada.

RE: FLASHBACK’S
Hallucinogen persisting perceptual disorder (HPPD) as far as I know is only consequent to the use of LSD
(& very rare). I am not aware of documentation that mushrooms cause flashbacks. This effect could well be related to sensitization of brain dopamine systems, a well known phenomenon, which could occur with LSD but is unlikely to occur after psilocybin because of differences in their mechanisms of action.
There is no evidence that hallucinogens produce mental illness in anyone not predisposed to it. That is, persons who experience the onset of psychosis would likely have suffered it in any case; hallucinogens may expedite the process. LSD is most problematic in that regard because it also activates dopamine pathways in the brain; the same transmitter that is believed to be involved in psychosis. Psilocybin does NOT activate dopamine pathways.
So Joey if you are going to write articles about things you know nothing about, Please dont, The Number one problem we face today with drugs .. is mis-information & lies, young people need information but that information must be correct, so that they can make an educated decision as to whether something right or wrong
