They can certainly make one. But usually losers are losers with or without drugs, they just boosting effect.
As Le petit says times are different, kids these days doing drugs much, much more than in 80s. And yes sliders doing and for sure legionnaires doing. As 666 confirmed , he said that some guys can't wait for weekend to get hit of coke. OK he said in his style
that
everyone are on cocaine and heroin which of course is not true.
What are the reasons of such increase for drug usage? Who knows, there is multiple possible. Overflowed drug market with drugs becoming easily available and cheaper. Back in days teenagers in heads had different concept of drugs than kids today. In 70s, 80s we had only certain groups of young (and old) people widely accepting drugs, today is totally different. One don't have to be hippie to do drugs today.
That's why I'm getting little bit pissed when I hear about 0% tolerance policy in armies (especially FFL). That simply isn't feasible in this day and age. Of course army should not allow to have stoned people with guns running around, but also I don't think that someone should get kicked out just for one positive test on some illegal substance.
