found it. it is part of the proposed cannabis law
Post# of 75010
the actual text of the proposed law is even more strict than what is said here. I think mexico will only allow big boys IF and only IF the low-income individuals, small farmers, and indigenous peoples fail at producing....not gonna happen ;p
7. Big businesses won't have licensing priority
Another important thing investors should know is that major North American cannabis businesses aren't going to be given priority in terms of being awarded licenses. The draft legislation calls for low-income individuals, small farmers, and indigenous peoples to have licensing priority in Mexico. This is likely being done to ensure that Mexico's economy, and not foreign companies, benefit most, as well as keeps the Mexican recreational market as competitive as possible.
