Persusive Essay Help

I'm doing my persuasive speech on banning synthetic drugs, as in bath salts, synthetic weed, and stuff like that. Can you guys provide me links to sites that go against this stuff or tell me some bad stuff about them?

 

Not sure about websites and such, but as far as essays are concerned, remember for persuasive essays to not use the word "I" and use credible sources and quote people and such.
