PHOENIX — PHOENIX (AP) -- Arizona's medical marijuana law doesn't allow smoking the drug in public places and a court ruling says people with state-issued cards entitling them to use cannabis don't have immunity in a car in a parking lot.

The Arizona Court of Appeals ruling Thursday affirms misdemeanor convictions of two people caught smoking marijuana inside a car parked near a Mesa music festival.

The court rejected the argument by Matthew and Elena Tagge that their medical-marijuana cards provided immunity from prosecution and said they ceded their immunity by smoking marijuana in a public place.

One judge on the panel cautioned that immunity still applies to a cardholder in a place that is traditionally private, such as a closed bedroom of a mobile home parked in a public lot.a linear actuator respectively. The linear actuator disclosed in EP0662573B1 includes a worm rod, a lead screw, a worm wheel set fixed to one end of the lead screw. The worm wheel set comprises a worm wheel. A helical spring surrounds the outer periphery of a cylindrical ring. In this way, the linear actuator can be obtained. In view of the problems of the EP0662573B1, the linear actuator disclosed in WO2004-027290A2 is provided with a heat-conducting element for dissipating the heat generated by the frictional force between the helical spring and the cylindrical ring.
However, in the conventional linear actuator, the helical spring is stationary, but the cylindrical ring is rotatable together with the worm wheel. Thus, heat is generated due to the friction force between the helical spring
