Tourists visiting Clifton Hill in Niagara Falls Sunday afternoon might catch a pungent scent.

That's because for the fifth year in a row, pro-marijuana activists will march through the tourism district and light up joints to protest the criminalization of marijuana and to demand that cannabis be legalized. Each year, hundreds of people gather where Highway 420 meets Victoria Avenue in Niagara Falls. They then march to Clifton Hill waving flags and inhaling from joints, pipes and bongs.

Police will typically send cruisers past them frequently, but otherwise leave the protesters alone.

At the Highway 420 website, organizers say Canadians and Americans need to join together to end what they say is the expensive and harmful prohibition of cannabis. Organizers say enforcing the prohibition of cannabis costs Canadian taxpayers $1.5 billion a year, that 60,000 Canadians are arrested for cannabis offences each year and that the criminalization of pot creates a situation in which organized crime flourishes through marijuana growing operations.

Rally participants are encouraged through the website to create and carry signs such as 'Organized crime, cops and politicians love prohibition, 'Prohibition breeds corruption,' and 'End the hypocrisy: legalize marijuana.'

Sunday's rally begins at 3 p.m.
