Suboxone was designed to get people off opiates and it has a ceiling effect after about 4 mg so he is really wasting his time chasing the dragon with this one because it's really not meant to get high on. It is also very addictive and hard to get off of. See if you can get him to come on here and just read some of the others experiences with the drug. I took it for 4 years to get off hydro, spent $6000 to detox from the suboxone. It has it's place in the scheme of things, but it is a waste if all he wants to do is get high.
I see now from your other post that it's your boyfriend doing this, I answered your other post. Would he be willing to come here and get some help? Does he want help at all?
They are now trying to phase out the pills and have people use the films. Of course it's harmful to your health and if in fact you are not used to using anything at all it can kill you. I would NOT do this, stay far far away from it :)
