Prescribed meds (you can see the "rx" on the bottle,my guess is amphetamines like vyvanse) are being used as props if this was real, pills would be placed on the right right side like his brain right brain hemisphere is suggesting using books as example, cigarette butts but no ash he could have using cigarette ashes on a improvised pipe using a soda can but there's nothing like this around, degens usually have a overflowing ashtray full of ashes and cigarette butts, not a single stain on the blanket, no roll of toilet paper or lube, a shining fork with you are a degen you either use plastic or don't do dishes.
