Marijuana is Bad for the Environment
Besides a single marijuana plant needing a minimum of 6 gallons of water a day and most indoor grow sites using enormous amounts of electricity to keep grow lights on 24 hour a day to create a non-stop growing cycle, the environmental practices of most in the marijuana industry are loose at best.
You will hear pro-legalizers say, “Environmental concerns can be cleaned up once pot is legal.” This is not true, and there are many reasons why:
Most legalization bills are written and passed unknowingly by the public without funds dedicated to enforcement or clean up.
Environmental funds for clean-up in California alone are estimated in the $50 billion range
The black market would have to be eradicated at the same time to effectively eliminate the damaging environmental practices; no state is organized nor funded to eliminate the black market (another pro-legalizing myth).
State and local government's generally do not have extra funds laying around waiting for a use to materialize
As of 2018, no state government has brought in more than $250 million in taxes and fees from legal marijuana sales. $250 million is basically no money - barely enough to cover a rudimentary regulatory structure and certainly not enough to cover enforcement or environmental clean up in any significant way.
