What frequency is it safe to consume alcohol at? Last I checked, never, unless of course you want to cite studies funded by the alcohol industry. Your opinion is that MDMA is worse than alcohol. I don't even think it's in the same league. In my opinion and extensive experience talking with addicts, alcohol is by far the most destructive drug, worse than heroin (and other opiates/opioids) and even methamphetamine. It is most destructive to the self, mind and body, and it's certainly most destructive to society. MDMA has a handful of deaths over many decades and billions of doses whereas alcohol kills 2.5 million people worldwide every single year. There is no comparison.
