What makes it more alarming is that they're getting better at hiding drug abuse by coming up with new slang words and phrases for drugs, NBC 4's Amy Basista reported.

Kids are getting increasing better at hiding addictions from parents and they're doing it through language -- words most parents don't recognize.

Many teenagers now refer to drugs in code. Some may call cocaine, yahoo -- or Adam and Bean for ecstasy.

Heroin is also called antifreeze and sweet dreams.

Teens are getting drugs over the Internet, from friends or taking them from someone's medicine cabinet.

According to the National Institute of Drug Abuse, 2.5 million kids are using pain relievers.

That's one of the reason the CEO and founder of hairconfirm came up with an at-home kit that allows parents to take a hair sample and find out within 24 to 48 hours if their kids are drug free.

It can detect drug use and usage frequency for up to 90 days.

The hair sample is then sent off to a lab. You can remain anonymous. Everything is done through a specimen number.

The kits cost $89.99 and can be found on Amazon.com.

Other slang terms to look out for include locker room or poppers, which are slang for inhalants. Ketamine, which is commonly prescribed for migraines or used in veterinary medicine, can cause hallucinations and is often referred to as breakfast cereal or cat valium.

Steroids can be called arnies, a's or gym candy.
