Yes, the basic Islamic principle is that everything that is proven to be harmful is haram.

The evidence for the prohibition of that which is harmful is to be found in the Qur’an and the Sunnah.

Allah says in Surah Al-Baqarah:

“and do not throw yourselves into destruction”

In Surah An-Nisa:

“And do not kill yourselves (nor kill one another)”

The prohibition on killing oneself is also a prohibition on the means of doing so. Whatever causes harm is haram.

The Prophet (blessings and peace of Allah be upon him) said:

“There should be neither harming nor reciprocating harm.”

  • Is there consensus on this? Or do some consider it makruh instead of haram or even mustahab to not do it?

    @Uma Actually this answer was taken from user Casanova, I didn't write it. I think he got it from IslamQA. I think this answer here goes through a similar subject in more details: islam.stackexchange.com/a/39803/15201
