Of course they're not illegal........they can be taxed at a ludicrous amount - I said it before, if the Government could work out how to tax them then drugs would be legal.

Legalise all drugs, licence and oversee suppliers to ensure purity and tax heavily. Sound familiar? It's what they do with alcohol and nicotine, those "good" drugs.
Would make a fortune for the country, cut out a whole element of criminal society and improve the health of thousands.
