Denver: "Meet the 'Nasal Rangers'"

"Pot smokers in Denver, Colorado - where the limited sale, possession and growth of recreational marijuana is legal - have had their noses put out of joint recently by Public Health agents dubbed the 'Nasal Rangesr', whose job is to sniff them out."

Denver Department of Environmental Health officer Ben Siller uses his 'smellescrope' - proper name Olfactometer - to detect marijuana odor and then investigate whether the law has been broken based on the strength of the smell.

Siller, who has been investigating odor complaints (not restricted to marijuana) for 26 years, told 7News that his job is primarily to call out businesses that grow marijuana and are affecting neighbors and passers-by with the plant's stench.

According to the Denver Post, the odor has to reach a level of 8:1 in order to receive a fine of $2000.

Such a violation has not been reported since 1994.

'It has to be a very strong odor,' Siller said.

A major issue in Denver at the moment is a proposal to make the very smell of marijuana a public crime.

'Odor can be subject' said Mary Beth Susman, Council President.

'It's hard to legislate odor.
'The strength that is required to register on the Nasal Ranger is something we need to look at.
