Legality

Cannabis is illegal to possess and cultivate in most countries. However, recent research into its medical benefits have revealed it is a relatively benign and mostly harmless substance. Many countries, including the UK, Portugal and Canada, are re-evaluating the plant's legal status.

in the US

Cannabis remains a Schedule I drug in the United States, along with LSD and heroin, carrying the severest federal penalties for possession and supply.

in the UK

On January 29, 2004, cannabis was reclassified from a class B to a Class C drug. Class C is reserved for substances with an accepted medical use, such as steroids, anti-depressants, and some tranquillizers.

Note: it's still illegal to possess or cultivate the plants. However, if you're caught with cannabis, police can give you an official warning, rather than cautioning or charging you with an offense.

You can be arrested if:

* you are publicly smoking

* you've previously offended or been given a warning

* you are aged 17 or under

* you are close to schools or other 'youth premises'
