Dogs Regard Positive Energies as Normal

Anonymous:
A dog trainer I know uses synthetic narcotics and explosives for training. I recently helped with a session, and when he opened the narcotics kit, I felt sudden forehead tension. I’ve wondered if storing synthetic substances like these at home could have a disruptive or negative energy. I also saw a video claiming tattoos can act as energy “portals.” I tried to find if Almine has spoken about the energy of synthetic substances or tattoos but found nothing.

My questions are:

1. Is storing synthetic versions of substances (narcotics/explosives) in a home energetically disruptive or harmful?
2. Are tattoos energetically problematic (e.g., do they act as portals), and are there sigils that can help neutralize those effects?
3. Would dealing with the energy of tattoos or synthetic substances require a personal sigil, or is there a general one that applies?
4. Can dogs be trained to track or detect positive energy states (like “glad expectations” or “innocence”), and is this a meaningful path to explore?

The Seer:

1. Yes, is it harmful and I have found that years after exposure by workers in a chemical plant, they are still being affected, particularly in having a low immune system. 
2. Tattoos using lead in the ink cause mental defects, but when this is not the case, everything depends on the topic of the tattoo: poisonous flowers can cause toxicity, nonpoisonous flowers do not for example. 
3. A Powersigil could prevent a tattoo of a destructive topic, from tracking similar energy.
4. Dogs regard these positive energies as normal. They embody these principles of innocence, etc. It would be possible to train them to show avoidance for negative emotions, but not positive ones.
