It really depends upon the facility ... often they allow smoking in a confined area and under supervision...and no one is allowed matches but the aide.

Sugar and caffeine make most ppl hyper... and sometimes effect the results of a medicine for depression and other disorders. They keep the place ice cold to keep everyone calmer than normal... so of course giving sugar and caffeine could defeat that purpose too!

Music is such a personal choice, the number of complaints and arguments could be numerous. As for having your own instruments to listen with, or even laptops... well.. the liability issues are there if their damaged or stolen, plus you are to be working on healing, not distracting yourself with other things... Plus, you will notice that there are few things that can be thrown, and if thrown would cause any damage to a person or facility. That is for a reason too.

hope this helps...
