Authorities throughout New Hampshire are asking people to be aware of possible one-pot meth labs.

An article from WMUR says police have put out the warning because these one-pot meth labs are produced by using plastic drinking bottles to make methamphetamines.

Now that the warmer weather is upon us, that means snow has melted across many areas of New Hampshire and police say the bottles can easily turn up on the side of the road or even on lawns.

Officials say there could be sludge in the plastic bottle, or there could be some sort of tube protruding from it. Authorities say the contents could easily catch fire or even explode.

If you come across one of these bottles, you are advised not to touch it, but rather call police and they will handle the situation.

This is also a time where syringes, needles and other drug paraphernalia my be visible after being buried under the winter snow.
