DXM is not physically addictive and it does not cause as many deaths as cocaine,heroin,or crystal meth,and is usually abused by teenagers,and it is a legal substance available over the counter.I don't think it is close to the worst drug out there,but it is a dangerous substance to abuse.As far as millions of teens Overdosing on it I do not know the numbers,but I think that if you compare the damage done by heroin,meth,and cocaine to society and families and high crime rates,a drug such as DXM is not considered to be a "bad drug",although everyone with any commonsense knows that DXM is a dangerous drug ,but it is far from replacing heroin,meth,and cocaine by far.Even among teens pharmaceutical drugs abuse kills more than everything but alcohol.Very few people on here are young people who still take DXM ,as there are much more powerful and much more pleasurable substances in the world,although i admit DXM is a problem.
