Earlier quoted context omitted.
You do realize you can vape flower/concentrate and eat edibles, right? >Marijuana is a gateway drug, I strongly believe this but open for changing my mind if there is data supporting otherwise. The burden of proof is on you to show this. What you strongly feel doesn't matter.
The "gateway drug" assertion isn't an "all or nothing" issue. There's nuance to it. Ask a bunch of drug addicts if they used weed before [heroin|coke|speed|lsd| |aota], most of them will say yes. At least the ones I've been hanging out with in NA for the past 25+ years. Does that mean, smoke weed and you'll automatically end up using other drugs? No.
Correlation != causation. The idea of a 'gateway' drug is absurd.
The simplest explanation is that people with mental illness or trauma will self medicate. So given that, it makes sense that the easiest to acquire/least scary drugs would be the first used. I bet even more people got started on alcohol as their first 'treatment'. That doesn't make it a gateway drug.
