These discussions generally support the idea that cannabis use in Japan follows the use of legal substances like alcohol and tobacco, with posts citing scientific articles and expressing opinions about the implications, tone, and relevance. Words like 'debunked' and 'support' reflect active engagement, while references to scientific studies demonstrate their attempt to critically evaluate the research’s significance.

AgreementModerate agreement

Most discussions support the study’s findings, emphasizing that cannabis is usually not the initial substance, but follows alcohol and tobacco use, aligning partially with the study’s conclusions.

InterestModerate interest

The discussions show moderate curiosity, with many referencing the study and its implications, though some posts dismiss or dispute parts of it.

EngagementModerate engagement

Participants reference specific research articles and commentaries, indicating a genuine effort to analyze and debate the findings.

ImpactModerate impact

The discussions seem to influence opinions and highlight the ongoing debate about the gateway hypothesis, suggesting some level of societal impact.

Abstract in brief

  • This study examines whether cannabis serves as a gateway drug among users in Japan, where it is heavily regulated despite its historical medicinal use.
  • An anonymous online survey with 3,900 participants revealed that most respondents had used tobacco and alcohol before cannabis, and the odds of progressing to other illicit drugs after cannabis use were generally low.
  • The findings challenge the gateway drug theory in Japan, indicating that cannabis use often follows alcohol and tobacco, with many users not transitioning to other substances, suggesting that societal factors and strict drug policies influence these patterns.

Cannabis has often been labelled as a “gateway” drug, but more and more research has come out that proves the opposite. “Cannabis use in Japan typically follows alcohol and tobacco, and rarely leads to further drug use.” Read the research: https://t.co/jUk9or3r9b #legaliseit
