Oaksterdam University, the California school which professes to deliver quality training for the cannabis industry, was raided Monday by federal agents, the institution tweeted.

The school was trending on Twitter amid its announcement of the raid.

While Cancer.gov discusses the ANTITUMOR effects of CANNABIS (http://1.usa.gov/wtI6QU).. we get raided! #WTF #SaveOaksterdam, Oaksterdam tweeted around 4:30 p.m. EST. It smells funny & grows beautifully! It's never caused an overdose, but it helps people with multiple diseases. The truth will set it free!

Amid the raid by the U.S. Drug Enforcement Administration, Internal Revenue Service and U.S. Marshals, Oaksterdam University said it is not conducting illegal activity.

PLEASE RT! Oaksterdam is trending! Please tweet your support! Richard Lee & Oaksterdam are not criminals. #SaveOaksterdam #MeasureZ, the school said, referring to its founder.

Oaksterdam University is a portmanteau of Oakland - the city where its campus is located - and Amserdram, the Dutch city famous around the world for its tolerable attitude toward marijuana.

Medical marijuana is legal in California and Oaksterdam Univeristy trains users on how to deliver a quality product.

Oaksterdam was founded in 2007 and provides weekend seminars, semester-long programs, horticulture programs as well as electives.

Oaksterdam bills itself as giving quality training for the cannabis industry on its website.
