Absolutely, every individual has the same rights as every other individual. One’s rights end where another’s begins. Additionally, if this individual is as deadly as you fear, he won’t exist very long. Also, you and your neighbors could offer to buy the property and sell it to someone who meets your standards. And lastly, and remember I am assuming meth is legal to buy and sell, if meth is as deadly as you judge it to be, it won’t take too long for the best amongst us to realize that and avoid it like plague. As to worst amongst us, they will always find ways to destroy themselves, whether legal or not.
