I would legalize Hemp and offer industrial incentives for the many, many products which can be made from hemp including, nutritious oils, alcohols, deisel, and fuel combinations, as well as Rayon fabric, rope, cosmetics, nut butters, canary food and a thousand others.  But yes, I would  also legalize Marijuana both for Medicinal use and recreational use for legal aged adults of whatever any particular state considers adulthood.

I would mandate the use of a $100 water cooled de-superheater component on all new outdoor air-conditioning system condensers.   The end consumer can then produce 300 gallons of waste hot water per day, for FREE like in hot water heater and hot tub per ton of air conditioner kinda FREE.  You just eliminated 75% of your monthly energy bill at home and two or three years from now that 75% will be going directly in your pocket.
