Cooking substances is extremely dangerous and toxic.

I could say more about the abusive application of these laws, but that's a political discussion.You may have some toxic substance mitigation to do.

But these toxic substances may raise the odds of sickness even cancer to the nearby residents.Do you guys think it is a big deal to consider this problem?

Unless you're in possession or positive on urinalysis, it shouldn't affect you one bit.On that note, you should be very clear that there's no smoking (of any substance) allowed in the house.

In my opinion we have bad public policy in this country that leads to an over concentration of poor people in many urban areas, which then leads to high crime, substance abuse, poor schools, etc.  

I have NEVER done any illegal substance in my life.

History has shown that the FDA prefers to error on the "disapproving" of substances so as to keep American Safe.

The only thing that is discussed is old, regurgitated sound bite propaganda with little or no substance.
