DETROIT (WWJ) - Despite the passage of Proposal 1, one group says they will continue to fight against legalized recreational marijuana in Michigan.

Prior to Tuesday's vote, members of Healthy and Productive Michigan publicly lobbied against the ballot measure.

Although it passed, the group's president Scott Greenlee says the fight is far from over.

"The devil is in the details. There's going to be a lot of things that are going to be involved in going forward," Greenlee told WWJ's Jon Hewett and other reporters, pointing out that marijuana remains illegal under federal law.

"We recognize other states have kind of ignored the federal law; they've ignored the Controlled Substances Act, they've ignored international law and international agreements in this regard," Greenlee said. "We're not so sure Michigan's gonna."

Greenlee said he's already heard from two dozen community leaders who want to know what their rights are under the new law.

"Our committee has already been contacted by a lot of municipalities that want to opt out of this proposal," Greenlee said. "We're going to be taking a look at things from a legal perspective, a policy perspective and a practical perspective going forward."

Dr. Kevin Sabet, president of the nonprofit Smart Approaches to Marijuana (SAM), a national partner with Healthy and Productive Michigan, said he believes Prop 1 was misunderstood by voters.

"A lot of people were in favor of this because of the decriminalization," Sabet said. "They didn't necessarily agree with pot shops, they didn't necessarily agree with gummy bears. They didn't' necessarily agree with 99 percent concentrates that you can put in a pen and hide in a tenth grader's highlighter that nobody would know what's in it."

"So, you know, we think we need to continue to have that conversation," he added. [More from Dr. Sabet]

The law will take effect in about a month, as the election first has to be certified by the Board of State Canvassers. Ten days after that certification, people age 21 or older will be allowed to have up to 2.5 ounces on them, have up to 10 ounces at home, and grow up to 12 plants.

It will still be illegal to use pot public place or drive under the influence.

The process of establishing regulations for its retail sale could take about two years, after which sales will be taxed -- 10 percent on top of the six percent sales tax -- with the tax dollars going to schools, roads and cities where the sales take place.
