The present situation is that people are likely to consume substances with less information than they could have about its potential to do them harm because the origin, composition, and toxicity of the substance is unknown. I think it's useful to acknowledge, when we're discussing how to address this issue, what actually happens now. Drug testing already occurs, but it does so in a grey area. The testing sites are used, but they're far and few between—operating through volunteers unable to touch the drugs themselves, rather allowing young people to use the drug machines and avoid touching them because they face the risk of prosecution through possession or supply.
