This is the irresponsible use and very adolescent and even psychically dangerous to the user.
Mushrooms, et al, are to be treated like a "sacrament", (all Jesus aside here) in the sense that one prepares carefully, gets information and guidance from the knowledgeable and experience prior to the experience. One usually has some goal or insight before hand, (peace, healing, mind expansion, etc.) if it is to be done in the most optimal and beneficial manner.
Set and setting are very important and having a "babysitter", (as we used to call it) shaman or guide is really advised, especially for a novice having an introduction to entheogens.
If we are going to free the "sacraments" from illegality, that will require better understanding and education with a strong emphasis on preparation. Otherwise, you get the socially problematic results across a wide spectrum which just put a negative bias on what can be profoundly healing and life-changing substances. Having a truly "spiritual" mushroom journey represents a world of difference from religious "ideas", beliefs, dogma, etc. It can be intimate, somatic, transformative, etc.
Usually, one does not keep rapidly taking it, but rather, a period of weeks or months should be allowed to elapse after a really deep experience with the goal of integrating it.
Recreational use is not necessarily bad and there are hedonistic enjoyments, but reckless use with these substances make them more risky and give the public the wrong impression. We need to come out of the Dark Ages and rediscover the psychological value of them.
