Is it permissible to take Captagon and perform prayers, even though it does not incapacitate the mind and increases focus, despite its many drawbacks?

Captagon is a narcotic pill and its consumption is impermissible. For the prayer to be valid after taking stimulants, the mind must remain conscious, such that the worshiper knows what he is saying, in accordance with the Almighty's saying: "O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying" [An-Nisa: 43]. It is not permissible to consume stimulants if they cause health damage or lead to a loss of one's faculties.
