It is dangerous to do with friends rather than doing it by one person, the effect of stimulant is enhanced by co-ingestion and it becomes easy to depend.

Outside medical applicationsStimulant(Kascaisoi)The use of is a crime in any country, it is best not to put out hands either for yourself or for the surrounding people, but even when you buy yourself a stimulant and use one's stimulant There are many cases that the dependents who make it is invited by their friends at the beginning and hands have been handed out in many cases, intake of stimulants is an act that has a social aspect as well as many other substance abuse. Their intake environment, which is often used with friends, may make people more dependent on stimulants.

Experiments with mice conducted at Keio University showed that when ingested with fellows, the effect of stimulant is enhanced and the risk of addiction (dandruff) and dependence is increased as compared with ingestion by alone It is known.

Details are as below.The stimulants are more dangerous when ingested with friends ~ clearly in experiments with mice ~: [Keio University]

Professor Shigeru Watanabe of Keio University Faculty of Letters, Professor Shigeru Watanabe examined the effect of social factors on stimulants using mice, the effect of stimulant was reinforced by co-ingestion with fellows, and the danger to addiction and dependence Has been shown to increase. "Drug-social interactions in the reinforcing property of methamphetamine in miceThe article entitled "Behavioral PharmacologyIt is scheduled to be published in magazine 22 vol.

In the experiment, we first put the mouse in an experiment box made up of three sections of white, gray, and black, and measured how much stay in which section. nextMethamphetamine(Hiropon) injected into the compartment, confined in one compartment and can not go to the other compartment, the next day will be injected with saline and locked in another compartment, then again three blocks will be free I measured the length of my stay. As a result, it was shown that the staying time in the compartment where the stimulant was injected became longer, and the mouse became to like the stimulant.

Next, in order to obtain the effect of social factors on stimulants, if you receive injections of stimulants along with their colleagues in the same cage and repeating the same experiment, the staying time in the stimulant injection section becomes even longer It is said that. In other words, this means that social encouragement has made me more fond of stimulants.

Furthermore, when you receive an injection of stimulant, if the companion injects saline, when you make an injection of physiological saline, if the companion receives a stimulant injection, the aforementioned social promotion is not seen about. Interestingly, it was also found that I got an injection of saline and that the staying time in the compartment with my fellows who were injected with stimulant was lessened, as for the mice not injected with stimulant It seems to suggest that you do not like to be with a mouse injected with a stimulant.

Even human beings, friends who do not use stimulants leave away from those who have become abusive of stimulants, so they only associate with "stimulant fellows", so it is happening that stronger dependence will be formed Maybe.
