Escaping is not working through. Time alone does not heal grief and if one goes "elsewhere"/into drug-induced feelings, (a) a drug that powerful has to be addictive (if only emotionally)/"in charge" and (b) nothing gets done on the grieving front, one just gets emotionally behind and that makes it hard to "catch up" to real/present Life as it is and, the drug re-enforces itself ("What's the use I might as well just use the drug and escape all this unpleasantness/difficulty catching up").

Who is going to pay for the drug and one's non-participation in society? Everyone has grief and difficult times in life. If we all check out, decide we just want to feel good instead of work hard to support ourselves, who's going to do the work to keep society and life running?
