Brief Answer:
These medicines will not affect your test

Detailed Answer:
Hello,

I understand you are very apprehensive about the hair follicle test.

In the United States, employers that follow SAMHSA testing guidelines generally test for five specific classes of drugs.
These drugs are:
Amphetamines (methamphetamine, amphetamines, ecstasy(MDMA))
Cocaine (Powder and "crack" forms)
THC (marijuana, hash, edible cannabis products)
Opiates (heroin, opium, codeine, morphine)
Phencyclidine (PCP, XXXXXXX dust)
Alcohol is occasionally tested for in addition to the above drugs.

Private employers may opt for an expanded test that screens for additional additional drugs.
The most common additions are:
Barbiturates (phenobarbital, butalbital, secobarbital, downers)
Benzodiazepines (Valium, Librium, Xanax)
Methaqualone (Quaaludes)
Methadone (a drug used to treat heroin addiction)
Propoxyphene (Darvon compounds)

The following drugs are detectable in a hair test, but are only rarely tested for
Hallucinogens (LSD, mushrooms, mescaline, peyote)
Inhalants
Anabolic Steroids
Hydrocodone (Oxycodone, Vicodin)

If you have not used any of the above, then there is nothing to be apprehensive.

Best wishes,

thanks I'm more calm. it's just that there's a lot of bad comments from people saying that I can come out positive because of the ear drops containing benzocaine and I have another hair follicle test after failing one in dec. that's why I was so concerned about it..
