I see anyone who lightly bandies about "John's drug use" as pushing the ongoing cover-up of what his life was really like and what happened to him. I think the facts are far more dire. I think John was caused to ingest toxic substances of some sort at times without his knowledge or permission, perhaps starting even before Yoko and May. I think the excessive drug use was a consequence of this...and the rages and weird behavior was in part a consequence of this... Hopefully, the truth is coming out now, so everyone can see and decide for themselves what to think...
