would you place your loved ones on a train, ship or airplane when you knew that there was no restrictions on the crew using drugs during the operation of that equipment?

Strawman. Legalization of drugs does not imply that operating vehicles while drugged is going to be legal.

Or that members of the crew had frequent 'flashbacks' from the abuse of certain drugs they used?

To my knowledge there are no flashbacks. It's a urban myth originating from the Reefer Madness propaganda. Got any sources for your claim?

Now lets change the scenario to smaller transportation vehicles, motorcycles, cars, light and heavy trucks. Would you allow your small children to play, walk alone or with someone who was infirmed on lawns or public sidewalks where common vehicles travel in close vicinity?

Do you argue here to ban all motorized vehicles. I know cars can be dangerous. But should we really ban them?

You would add the free use of drugs amongst citizens to this hazard?

The "how dare you" tactic. Nice.
You would jail free citizens because they choose to smoke/eat/drink something that is not "pc"? How dare you!?

Why, so I could be so stoned that crossing a street was exciting and extremely dangerous?

Yet another emotional argument without value.

Just a small side question..have you ever seen the corpse of someone who was hit by a car going sixty, or a train going ten mph?

Yes. Not a pretty thing. We should ban all cars and trains. It's for the children, you know.

It's a bitch when you have to consider that a very large percentage of drug users become addicts the same as alcohol users, isn't it.

Not everyone has the self control to keep a clear head when needed. If you are willing to pay all costs associated with anyone who abuses your plan, I will support you. If not, I will continue to be against you.
