The suit alleges that the iPhone and Android free app, Nestdrop, is a "flagrant attempt" to bypass restrictions contained in Proposition D, the medical marijuana law approved by Los Angeles voters last year.

Nestdrop links customers with delivery services. It started as an alcoholic beverage delivery service but added marijuana in November, promising arrival within an hour.

Pot delivery is currently only available in Los Angeles, but the company has said it wants to expand throughout Southern California.

Customers must prove they have a doctor's prescription and must be a member of a medical marijuana collective, although they can join a local one through the app.

The company said it works with local dispensaries that can provide pot in bud, edible and concentrated forms.

The lawsuit argues that the law only permits medical marijuana patients to pick up the drug for themselves, or for caregivers to pick up pot for their patients.

The lawsuit, filed in Los Angeles County Superior Court, asks a judge to permanently bar Nestdrop from arranging marijuana deliveries and fine the company that owns the app, Nestdrop LLC, $2,500 a day since at least Nov. 12.

In a statement, Nestdrop co-founder Michael Pycher said the company intends to fight the lawsuit.
