Every one broaching the topic in any possible way.

Here’s Johns Hopkins, one of the leading voices in American Medicine, saying gay men tend to use crystal meth. Here’s a meta study referenced in at least 30 textbooks(I stopped counting the books in the cited by section) saying all ‘sexual minorities’ are much more likely to have substance abuse issues, but bixsexual women are the most likely to be long term addicts. Here’s a more up to date article saying Trans people are by far the most likely to be long term addicts. That last one is only in one textbook but is directly cited in two organization’s drug policies.
