Soon voters will decide whether to legalize recreational marijuana in Michigan.
On Thursday the group Healthy and Productive Michigan spoke out against Proposal One.
The group says legalizing marijuana would make it more accessible for children and says the "pot of today" is more dangerous than the "pot of yesterday."
Scott Greenlee is the President of Healthy and Productive Michigan.
He said, "You're not talking about the Woodstock-weed of the 70's, you know that had 3-5 % THC. This particular proposal would actually allow THC levels up to 99%. They're unlimited, that's a real danger."
Proponents of Proposal One say the tax revenue created from recreational marijuana could be used to fix roads and help schools.
There are two other proposals on the November ballot; Proposal Two would create an independent commission to draw up voting districts, instead of the party that controls the legislature.
And Proposal Three would allow no- reason, absentee voting and other measures intended to make it easier for people to vote.
