The Government has responded swiftly to proposals that drug laws be softened, saying there is no way it will make any such changes.
The Law Commission has suggested that people caught with small amounts of illegal drugs for personal use should be treated more leniently.
The latest report from the commission also says judges should not automatically favour prison for people caught dealing drugs to friends on a small scale.
Generally, it says the law should seek to provide more treatment and education to drug users, rather than punish them.
The report finds a more effective way to deal with the harm caused by drugs is to take a less punitive approach in some areas.
However, it says the full force of the law should continue to be used against large-scale commercial drug dealers whose activities wreak havoc on the community.
Justice Minister Simon Power says the Government has taken a hard line in its approach to methamphetamine, also known as "P", and has no intention of softening the way the law deals with any drug users.
Mr Power says Prime Minister John Key has declared a war against "P" and any move to be more lenient towards drug users or dealers would run counter to that.
Other proposals
With regard to party pills, the report says manufacturers and importers should have to have any new substance approved before it is sold, as happens with other hazardous substances at present.
It says that unless the pills are banned, there should be age and advertising restrictions on their sale.
Other issues traversed include whether cannabis should be legal for medicinal use, whether the system under which illegal drugs are classified needs changing, and whether people should be able to be detained compulsorily for drug and alcohol.
