#3 and #4 bears out with basic logic.

You think those on drugs haven't been while drugged up a liability?
Operating machinery on recreational drugs, are you alright or impaired?

Doesn't all these mistakes and accidents on the workplace with inferior work cost a business money and perhaps hasn't some been caused to probably close like many of the auto manufacturers? Their abuse of recreational drugs while working on the production lines are of legend in books and newspaper articles.

If you get more and more addicted and useless people, you don't think you will be using our emergency wards and welfare system to access ou treasury?

You have to have a lapse in logic to exclude my points #3 &4.

If I wanted to, I could grow that list beyond that quite a bit.

So does alcoholism and lack of sleep; do you support a general ban on alcohol, and government-mandated bedtimes?

You have to have a lapse in logic to exclude my points #3 &4.

I didn't exclude them ... you dodged my response.

Feel free. Until then, you can't win a debate with arguments you haven't made.
