Colorado lawmakers rallied at City Hall posing their first attempt to curb the state's booming medical marijuana industry: owners of the some of the shops that sell pot.

Dozens of dispensary owners quote that abiding with regulations if they provided with uniform guidelines and avert a more severe crackdown like one approved this week in Los Angeles. Hundreds of Los Angeles pot shops face closure after the City Council voted Tuesday to shut the number of dispensaries in the city at 70.

At Wednesday's meeting, Councilman and committee member Pete Constant, a retired city police officer, prompted Oliverio's concerns about the "cost of inaction" as he witnessed the number of confirmed dispensaries in San Jose to have jumped from none a year ago to perhaps 30.

The Colorado proposal focuses preventing the recreational pot users to become legal medical marijuana patients. In addition, it would limit doctors from working out of dispensaries, regarding it as illegal for them to offer discounts to patients who agree to use a designated dispensary, and require follow-up doctor visits.

Moreover, dispensary owners would have to be licensed, pass a criminal background check and pay a $2,000 application fee along with $3,000 a year to renew licenses, as per the new norms.

However, many among the 150 people present at the hearing opposed the bill, posing jitters that they will now have to pay the hundreds of dollars on top of the $90 annual fee they pay to register as a medical marijuana user.
