I think a lot has been said here that is good advice - so I wish you good judgement in this. Remember we will still be here for the comforting words.

Two thoughts FWIW 1) you may already be aware of alcohol dementia - temporary amnesia etc - seen after years of booze abuse. 2) It is reasonably well documented that about 7 days after smoking pot there is often an aggresive phase. Though an aquaintance reckoned it was 5, then 12 days in her spouse's case, but maybe he was topping-up after the first kicked-in. Of course this depends on dosage.
