I do not think it will take increase health care costs for several reasons. 1) This country has jailed so many people our jail/prisons are bursting at the seams & all those prisoners have all their health care issues addressed without them paying a dime. Think of the money we would save not having to pay for their housing, food, water, electricity & health care. 2) Do not believe there will be a large increase in the number of people utilizing marijuana, talk to leaders of countries where it is already legal. 3) We would save money each year by not having to prosecute so many people on charges of possession. Save a lot of the courts time that could be better used for other cases. 4) Even a very minimal tax of say 1% would raise millions, if not billions, that we could use to reduce the national debt. 5) There are people that could use the marijuana for medicinal purposes that are now suffering due to lack of ability to obtain the product as they do not want to break the law.
