The Marijuana (HEMP) Party's West Australian Senate candidate has been coy about a reference to planting seeds in northern Australia.

Michael Balderstone has travelled from Darwin to Port Hedland as part of his campaign, talking to residents about cannabis and their use of the drug.

The party's press release also refers to him planting thousands of "seeds of hope and sanity".

When asked to clarify the statement, Mr Balderstone initially gave an ambiguous response.

"I suppose it's a bit of a pun, and I don't want to elaborate too much, but the idea is to educate people," he said.

"It's about education. People have been fed a lot of lies about cannabis."

Mr Balderstone was asked whether the reference was a metaphor, or if he had literally planted seeds.

"I think we'll call it a metaphor for this, thank you so much," he said.

"It is a metaphor."

Sex, hemp parties unite

Mr Balderstone is the lead candidate on the joint Marijuana (HEMP) Party and the Sex Party ticket, after the two parties last month agreed to a coalition.

"The new Senate voting laws have pushed us to join together," he said.

"We're both pretty progressive parties.

"If people haven't discovered marijuana and sex then they're in for a treat."

The parties will combine resources and votes in Queensland, Tasmania, South Australia, Western Australia, the Northern Territory and the Australian Capital Territory.

Mr Balderstone admitted his party's platform to legalise and regulate cannabis for personal, medical and industrial use would not be attractive to everyone.

"It's probably too radical for some people but we really need education," he said.

"Most of the weed we're consuming is grown by organised crime in a bath of chemicals.

"Hydroponic cannabis with tobacco is a whole other ball game to growing a plant yourself in your back garden.

"So many young Australians smoke pot with tobacco, it's a real trap."

Mr Balderstone said cannabis should be treated differently to other illegal drugs.

"I would love to see the Government have a drug summit and bring the whole war on drugs out into the open, discuss it with experts and get away from the law and order rhetoric," he said.
