I'm talking about consuming and carrying, not dealing. We can see the spanish law:
Article 25: 1. The consumption in places, routes, establishments or transports public, as well as the illicit possession constitute serious infractions to the citizen security, although he was not destined to the toxic, narcotic psicotrópicas substance or drug traffic, whenever it does not constitute penal infraction, as well as abandonment in the mentioned sites of equipment or instrument used for his consumption.
Here is the explain of you can consume drugs in your house, not in a public site, and the fine is not penal, only administrative (money fine):
The drug consumption or the possession of small amounts destined to autoconsumo does not appear like criminal acts in the Penal Code. Therefore, nobody can be condemned to prison or any other privative pain of freedom (house arrest, parole, etc.) to consume drugs or to have small amounts for its own consumption. Nevertheless, when the consumption or the possession destined to autoconsumo takes place in a public place, they constitute administrative infractions according to the Law of Protection of the Citizen Security and entail the imposition of a fine.
I'm just telling Pablo69 that there is no small amount of drug that does not entail a fine.
It is another issue what is the limit between drug for autoconsum and drug for deal
