So, I am given to beleive that since growing your own is now permitted in these states that more people will just grow their own as well and the numbers in tax revenue may be over inflated.
What I was responding to is the above quote, saying that you cannot simply grow your own for recreational use in Washington state. You have to pay a 1200 fee, and submit an FBI background check. Also these licenses will not be unlimited, so it is very unlikely that every person who wants to grow for themselves will be able to obtain a license. That is not the same as just being able to grow your own in your closet.
