Springtime means clean up time around Michigan, but at least one state sheriff's department is warning that there might be meth residue on that plastic bottle you're picking up.

The St. Clair County Sheriff's Department has issued a warning that some plastic bottle may have some methamphetamine residue on them.

Apparently meth heads use 2-liter plastic bottles to get their tweak on, so you may wind up with the drug on your hands, and that's not cool.

Their Facebook warning sound ominous:

Meth is made using the drug pseudoephedrine and common household chemicals, such as lye and Coleman gas. The chemicals are mixed in a two liter pop bottle. Once the chemicals begin reacting, there is danger of and explosion and fire. The danger doesn’t end there. Once the user gets the drug out of the bottle, it is discarded. Sometimes the bottles are thrown in ditches or yards. If a person picks up a bottle containing meth waste, the chemicals inside can re-activate, causing an explosion and fire. Also found at meth dump sites may be gas generators. These are containers with holes in the top with hoses coming out, which may be dangerous as well.
If you see a two liter pop bottle with a milky substance in the bottom, don’t touch it. Immediately leave the area and contact the Sheriff’s Office or your local police agency. We have deputies specially trained to dispose of these dangerous chemicals.
We have had no reports of meth lab waste so far this year, but want everyone to stay alert, so we don’t have any injuries.

I guess the best course of action would be to avoid any plastic bottle that is more than a little discolored. But please don't let this sway you from picking up litter.
