A conviction for the possession of marijuana in New York is unlikely to affect your car insurance, unless the conviction also involved driving under the influence. Car insurance companies seldom raise rates or drop coverage based on convictions that are not traffic-related. However, a conviction for driving under the influence of marijuana is likely to increase your car insurance rates, or force your insurer to drop you. Your specific outcome will be determined by your individual car insurance carrier.
