I could be wrong about this, but the personal use of marijuana has probably neared its peak. There may be some who will decide to abuse marijuana when it is no longer illegal, but as with the end of Prohibition, by the time marijuana is generally legal, all the people who want to smoke weed will already be smoking weed.

All 57 + Hawaii and Alaska
You can legally smoke it in Maine in your own home, You just can’t buy it as the state has not set up the rules for sale. They have also muddied the waters by changing the rules for medical marihuana. Most people are working under the med rules so recreational pot sales really won’t make much difference.
