A company in California is touting a new home-based hair follicle drug test kit called HairConfirm Prescription that is supposed to detect drug and prescription use and how often the person has used in the past 90 days. The company is targeting it to parents who now can pluck a hair (or get one from a brush or a pillow) and confront their kids' drug abuse (or confirm that their kids are clean.)

Biotech Company Confirm BioSciences launched the kit last summer and says it is better than saliva or urine screenings where users can escape detection by not using the drugs for a little while.

It tests for 12 different types of illegal and prescription drugs and measures the molecules embedded inside the hair shaft, eliminating external contamination as a source of a positive result. And the test results can't be altered with shampoos, bleaches or other external chemicals, according to the company.

"HairConfirm is designed to help parents take a proactive role in preventing their children's illegal and prescription drug use," said Zeynep Ilgaz, CEO of Confirm BioSciences. "Talking with your child about drugs and taking preventive measures like hair drug testing can be a significant factor in preventing substance abuse."

According to the U.S. Department of Justice, Bureau of Justice Statistics on Drug Use, more than 30 percent of teens surveyed in 2006 had used marijuana in the past year and nearly 85 percent said they could easily get their hands on the drug. Nearly 50 percent or more said they could easily get crack or amphetamines.

You can buy HairConfirm Prescription from Amazon and other resellers. The kit costs $89.99 (though Amazon advertises a used one for less) which includes a collection kit, prepaid return envelope, lab fee, report and free counseling hotline.

What do you think? Would you buy the kit and test your kids for drugs?
