According to a press release put out by the Harrisonburg Police Department in the wake of Underhill's death, the homemade brew’s potency can vary from batch to batch.

THE DANGERS OF 'POPPY TEA' Poppy tea is a herbal infusion brewed from poppy straw or seeds. Side effects include drowsiness, stomach ache, lethargy, urinary retention, constipation, and nausea. At higher doses, it becomes dangerous and can cause death through factors like respiratory arrest or inhalation of vomit. Frequent users can become dependent and withdrawal can cause cramps, insomnia, craving, lethargy and mental problems. There have been a number of deaths reported from the drinking of poppy tea, including a teenager from Nova Scotia and a young Tasmanian man, both in 2012. Advertisement

‘This is something new on the local scene that students and parents should be very concerned about,’ Lt. Kurt Boshart said in the statement. ‘It is not illegal to purchase or combine any of the constituent materials, but the end product can produce serious and even deadly reactions in anyone who drinks it.’

There are numerous blogs and websites containing a wide variety of recipes for poppy tea, which promises a hallucinogenic high.
