No, we should have the political will to remove the drugs from our streets. I'm sure the authorities know who the dealers/importers are and are most likely to be. I honestly think that it is such a lucrative black market business that the government turns a blind eye or lacks the political will to enforce the law.
Hold dealers accountable (to an extent - people deal to make a living so have a little empathy) but those who are addicted should not be penalised but rather institutionalised for rehab and given the opportunity to get back in their feet.
Yes for some/select drugs (not all). Yes to all if safe to highly-regulate and tax. Sentences should be reviewed, consider sentences that 'pay back' to society, and not cost society (Ie. Health/welfare costs of inmates)
Yes however it is always circumstantial. By decriminalising drugs it put limitations on illegal dealings and businesses. If the drugs were from a reliable source the use and amount could be monitised and by knowing what it is and where its from will ensure the health and safety of users as the drugs wont be laced with unknown substances
