i dont' think that parents who use methamphetamines should be caring for any children. at any age. it is not the smoke but the drug use that is the problem. it is difficult enough being a parent but when the parent is chemically impaired (even if they think they are not) it can be dangerous. in older children watching their parents smoke crystal meth is not the best modeling as you know.
what effects does meth have on children when the parents smoke it around them im the grand father
