INNOVATION isn’t the only thing the tech types in Silicon Valley are high on, if a report out of Business Week is to be believed.

The medical marijuana business is ablaze with customers from tech giants, the business publication reported.

One dispensary, Palliative Health Centre, based in San Jose, San Francisco, said that tech types make up 40 per cent of its customer base.

“We’re seeing people from some semiconductors, lots of engineers, lots of programmers,” assistant manager Ernie Arreola said.

The shops are around the corner from some of the area’s biggest names including Google, Adobe Systems, Apple and eBay, Business Week reported.

“Also, people in Silicon Valley do like their pot.”

Doug Chloupek, CEO of dispensary MedMar Healing Center, called marijuana a “functional drug” that helps a lot of computer coders code for hours at a time.

The dispensary offers marijuana-infused chocolate toffees that Mr Chloupek claims gives coders what they need to get the job done.

“Those who are coding for 15 hours a day with cramping hands, that is the product that allows them to have mental clarity and still get pain relief,” he said.

But you can’t exactly just walk into a dispensary and ask for a hit. You need to be given a “recommendation” (note: not a prescription) from a doctor for relief from migraines, arthritis or “other illnesses for which marijunana provides relief”.

According to Mark Johnson, CEO of Zite, a company owned by Time Warner, marijuana is so common that “you don’t need to hide it”. However, companies don’t exactly want their workers getting high on the clock.

Both Adobe and Cisco forbid the use of illegal drugs on work property, during work hours or on business trips, but neither company administers drug tests.

That’s a relief because from the sound of it few people in Silicon Valley could pass a drug test if asked.
