I'm a grandmother, looking for answers as to why my 20 month old grandson would test positive for methamphetamine in a hair follical test. Do you have any suggestions? If the prescribed medications he is taking would not cause this, what would?
Expert:  Dr. Phil, MD replied 5 years ago.

Why did he have a hair follicle test?

Child Custody Case...The child's mother had him tested. She's accusing the father of doing drugs. Lab results show 1.5 inches in length (approx 0-90 day time frame) Positive for Amphetamines/Methamphetamine 500pg/mg
Expert:  Dr. Phil, MD replied 5 years ago.
it seems as if the child may have been exposed to drugs then.
Customer: replied 5 years ago.
That's what the mother is claiming. I just don't believe it. The mother is currently taking prescribed medication for ADHD. And I don't have access to non-prescription drugs she may have given the baby.
Expert:  Dr. Phil, MD replied 5 years ago.

Prescribed medication for ADHD could show up as methamphetamine in a drug test. That is certainly possible.

I can't say for sure what is going on but its clear that none of the child's meds would be causing it.

Customer: replied 5 years ago.

If the child's prescription meds are not causing it, what other means could the child have be exposed?

Expert:  Dr. Phil, MD replied 5 years ago.

1)mom's medication

2)Dad doing drugs and child getting into them or exposed to smoke from meth
