Why? Are yoou so certain of the minimal negative results, to invite the homeless addicts to camp n your yard, or in parks in your neighborhood?
IOW I believe the current explosion of homelessness (drug addiction) results directly from permissivve drug laws and enforcement.
I have yet to encounter anyone who is "addicted" to marijuana. No one. This isn't about decriminalizing ALL illegal drugs, this is specifying marijuana which has definite medicinal properties. People spend years in prison for possession or using, yet we don't put people in prison for possession of alcohol; in fact, you can freely go to any liquor store and purchase as many bottles as one wishes.
I reflect back on a program that has been utilized in Belgium; in short, those who are caught with 'drugs' have two choices; jail time or rehab time. The success rate has been significant. They are seeing a reduction in addictions and drug use. I say they've got it right. We are still punishing the addict and users instead of insisting that they get help and offering them the help they need.
