Some of the substances that could be abused by traders are:
- Alcohol
- Energy drinks and Caffeine.
- Cigarettes, Cannabis and even cocaine. etc
Substance abuse can affect the accuracy of your trading decisions, so I feel people interested in trading need to understand this risk before starting to trade so that they do not turn to substance abusers, but rather focus on the healthy alternatives.
I haven't see someone that is irresponsible and at the same time a perfect amen to get a particular job like trading. Alcohol is the least thing I'm going to think about if I'm trading, I haven't even see any person from any expert on YouTube or any social learning about trading. I also don't like energy drinks, you will get use to it like an addiction and cigarettes, I don't like the smell. The things you have listed their, I don't think any sensible person will try this while trading.
Taking any of the above you mentioned is like you are trying to start another problem for yourself. These are sorber things when you have lost everything you started and who knows, there are people that has lost more than they will ever make but don't even show any signs to the extent they start taking something because it wouldn't bring back the money that has been loss and it wouldn't bring solution going forward, it's better to face the challenge completely.
