Thanks all for sharing your opinions.
I can only speak for me, but if I did decide to start smoking dope (Which I have done in the distant past), the next logical step in my alcoholic mind is "Hey this is nice, I could probably handle a few beers every now and then and use smoking dope as way of not returning to my alcoholic drinking."
In reality I know that smoking dope is out of the question for me. I recall being stoned, I darn sure did not have the peace and serenity I have in being clean and sober.
