A few run ins with drugs? I’d bet dollars to donuts he and his band mates did drugs ALL the time in the 60s, 70s, 80s…
I went to many many rock concerts and drugs were part of the lifestyle for better or worse. Of all the rockers I saw one and only one always gave an anti drug message at the very end of his performance and that was Ted Nugent. Saw him in 75, 77, and 78 iirc and all 3 times the very last thing he said before the lights went out for the final time was “Don’t do drugs!….that’s right, you heard me right, don’t do drugs!” Then lights out! No kidding.
I saw the Stones twice and they put on a good concert both times.
Mr Watts along with the rest of the band became highly successful in his mid 20’s or so. I’d say being highly successful at what you do for 55 or so years is a life well lived drugs or no drugs! RIP
Edit:Imagine if Mozart had lived to 80!…
