Entities that give feelings of drugs?

Because of the laws, I am unwilling to use drugs. Is there any magick that can give me the feeling that I would get from opiates?

I hope you’re not referring to these symptoms:

Agitation
Anxiety
Muscle aches
Increased tearing
Insomnia
Runny nose
Sweating
Yawning
Abdominal cramping
Diarrhea
Dilated pupils
Goose bumps
Nausea
Vomiting

But let’s get more serious of the “highs” of spirit interaction, because you actually can get “similar” effects without putting some illegal stuff in your body.

The energies of a spirit or an entity is, atleast for me, usually very high at start. It can be warm, cold or “neutral” in it’s physical manifestations. If you interact with the high(warm) or low(cold) energies, it can create a “rush” and even ecstatic moments within these kind of interactions. But like any drugs or alcohol abuse, you get a resistance to it, even if the energies is the same or higher. Your body and mind “adjust” to comprehend the energies better.
