A well presented document is needed. One that can be viewed online and addresses how the introduction of cannabis affects the other rules in place.
Take australia for example...
1. At what age can you legally try cannabis if its introduced, tobacco is still restricted to under 18's.
2. Can you drive under the infulance of cannabis. Drug testing is in place over here and will become more frequent and accurate.
3. Are we talking government manufactured or home grown and if so what is the size limit.
4. Exactly were can and were not is it acceptable to smoke cannabis. Tobacco is now illegal to smoke in clubs and pubs over here.
and there's many more individual questions that will be asked by the public.
