From a dream interpretation website:
Testicles :
If one dreamt his testicles were big his power and money will increase.
If dreamt his testicles were cut means the enemy will overcome him.
If dreamt pulled out his left testicle and threw away , means his child is in danger.
If dreamt gifted his testicle to someone means his child is by a cheating.
If dreamt his testicle was swollen or had hernia means will receive a big money but he is in danger.
If dreamt his testicles were long and were pulled to the ground means a big money.
If dreamt gifted his testicles and the other also gifted his to him, means both of them will cheat with others wife.
If dreamt was peeling his testicle someone will suppress to his child.
If dreamt someone pressed his testicle and he was unconscious means there is a danger for his child or losing dignity.
If dreamt his testicle was tied with a rope means his business will be closed.
If dreamt about someone else's testicle means overcome the enemy.
If dreamt his testicle had a failure means a sorrow.
If dreamt cut under his testicle means his power will be cut.

I don't see any mention of inhaling/sniffing/snorting but I still found it intriguing.
