RE:heres another chart - https://www.statista.com/statistics/58Goodness you need to learn how to read an article. Only users who smoked pot weekly spent that much - which was only around 20% of responders. 50% of responders used 2-3 times per month OR LESS. One gram a month would get you 2-3 uses. thats ten bucks and thats existing users. When pot becomes legal, all of the additional users are more likely to be low volume users. There will be plenty that pick up a big habit but not percentage wise.
Your second stat is based on medical marajuana users who are naturally going to smoke more than joe blow who smokes recreationally once its made legal. That will drop your amount spent significantly if you included all populations and user types.
Please read stats and think about what they represent before you post them.
