GREENWICH — Police made a motor vehicle stop in Riverside Saturday night, and officers came across “a thick cloud of marijuana smoke exiting the window” and five motorists drinking cups of codeine-laced soda, according to the arrest report.

After pulling over the 2016 Mercedes-Benz on East Putnam Avenue around 11 p.m. for allegedly speeding, officers said the men exited the vehicle carrying cups “that had a bright green substance suspected of being a mixed drink of soda and codeine cough syrup,” according to the arrest report.

Codeine-mixtures are called “lean,” or “purple drank,” or other terms in street slang. The cough syrup used to make the concoction requires a medical prescription, and police said the suspects in the Riverside traffic stop were not taking the liquid for medicinal purposes. Marijuana was also found, as well as bottles of codeine, the arrest report stated.

The five men were cited with various drug charges.

Jose Cruz, 23, of West Avenue, Bronx, N.Y., was charged with possession of narcotics. The driver, Leonel Cuevas, 23, of Webster Avenue, Bronx, N.Y., was charged with driving under the influence and possession of marijuana, as well as speeding. Joel Mora, 19, of Washington Street, Bronx, N.Y., was charged with possession of narcotics. Fredderin Santos-Pena, 19, of Presidential Boulevard., Patterson, N.J., was charged with possession of narcotics.

Leudy Reyes, 29, of Webster Ave., Bronx, N.Y., was alleged to have pre-packaged packets of marijuana, Oxycodone and promethazine cough syrup in his backpack. He was charged with operating a drug factory, possession of narcotics, possession of a controlled substance and possession with intent to sell. His bail was set at $2,000; the others had bail set at $500.
