Caution
Stimulants increase respiration rate allowing for a higher dose of sedatives than normal. If cocaine wears off first, recreational dosages of DPH may overcome the individual and cause respiratory arrest. Both substances at recreational dosages strain the heart and may lead to further dangerous heart complications. When taken together, both substances can potentially be more reinforcing and have greater risk of methemoglobinemia when higher dosages of DPH are combined with cocaine.
The risk here is to the experience — intensity, panic, thought loops, confusion. Physical harm is unlikely at ordinary doses. Setting, company and dose do most of the work.
