More serious offences are supply and intention to supply. Remember, supply includes giving or selling drugs to a friend, or even looking after them for someone else. People who say, 'the drugs were not all for me, some were for a friend' usually make things worse for themselves by admitting supply. The heaviest penalties under the law concern the import and supply of controlled drugs. Making or growing your own Cultivation of cannabis is also an offence.
Penalties are more severe if the court believes cultivation was intended to supply others.
It is not an offence to possess cannabis seeds. Manufacturing illegal drugs will be dealt with severely, usually in excess of what is given out for supply. Some drugs which are not illegal to posses such as Ketamine, GHB, herbal ecstasy, or poppers are covered by the Medicines Act 1968 which means that it is illegal to manufacture or sell such drugs without proper authorisation. Prosecution and punishment There are numerous factors to take into account in determining the likely punishment for any particular offence. Different police forces have their own approach to drug offences.
