Synthetic Cannaniboids can be bought from your local corner shop, then easily supplied to anyone. They’re not illegal to carry or sell so no laws are currently being broke. These are very dangerous drugs that have can have potentially life threatening effects on people adults and kids.
Society has enough issues dealing with the 2 biggest legal drugs alcohol and tobacco the issues with these though tend to be long term health problems. Spice and the likes can have an effect from the single use and trust me it is not a pleasant thing.
So while the ban won’t get rid of them totally, no one believes that, it’ll make so you can’t just walk in and pick some up with a pint of milk.
I dont see what that has to do with kids doing drugs/alcohol and where they get it from and how easy/hard it is.
Because that was some peoples defence for keeping spice.
