California school officials are warning parents about a new addictive street drug called "Paint." 

According to KOVR-TV, administrators at Mesa Verde High School in Citrus Heights sent a letter to parents regarding students secretly selling the pill, which reportedly has psychedelic effects.

The station said that officials are urging parents to engage in a dialogue with their kids about Paint, especially as the drug has caused violent incidents at school.

"Please know that Mesa Verde High School Administration is actively investigating this concern and we are making progress. We are asking for your support and help," read the letter, which was obtained by CBS 13 Sacramento.

The drug, which allegedly sells for just $5 a pill, is described as clear with a reddish-brown dust. 

The school's leaders are asking for any additional information about Paint as they conduct their investigation.
