Abswelto si Nadia Montenegro sa alegasyong paggamit ng marijuana sa loob ng Senate of the Philippines noong August 12, 2025, ayon sa abodago niyang si Atty. Maggie Abraham-Garduque. Naghain si Montenegro ng reklamo sa Pasay Prosecutor's Office laban sa Senate Sergeant-at-Arms officer na si Victor G. Patelo, kaugnay ng Unjust Vexation at paglabag sa Safe Spaces Act (Republic Act No. 11313) na kilala rin bilang “Bawal Bastos” Law. Ayon sa resolusyon, pinaghinalaang naninigarilyo ng marijuana si Montenegro, na noo'y Political Affairs Officer ni Senator Robin Padilla, dahil umano sa “unusual odor” mula sa palikuran na ginamit ng aktres, na mariing na pinabulaanan niya. Napilitan si Montenegro na ipakita sa security personnel ang laman ng kanyang bag at bulsa na naglalaman ng vape. Binalaan naman ng nagsumite mismo ng incident report na si Patelo na maaaring may "naiinggit" sa aktres. Pero tinuloy pa rin nito ang paghain ng ulat, kung saan pinangalanan niya si Montenegro bilang subject. Dahil dito, sinabi ng kampo ni Montenegro na nagdulot ang insidente ng trauma at matinding pinsala sa kanyang reputasyon. Pahayag ni Atty. Abraham-Garduque, "Congratulations Nadia Montenegro Pla. This is an early gift for you before Women's Day on March 8. "The resolution categorically stated that despite the fact that he knew that you were not smoking marijuana in the Senate of the Philippines on August 12, 2025, the respondent made an incident report which became the basis of the widespread false news against you last year not only to your extreme damage and prejudice but to your family as well. "This is a testament that albeit you are a woman, you can fight so that YOUR TRUTH can be heard. "I know what you have gone through and I am very happy to be your lawyer so that this vindication will be given and finally be given to you. “This revelation of her truth is the start of healing for Nadia." Kasunod ng isyu, nag-resign si Nadia sa kanyang posisyon bilang miyembro ng staff ni Senator Padilla para maprotektahan ang kanyang mental health at kapakanan ng kanyang mga anak. Aniya, "My decision to resign should not be misconstrued as an admission of guilt—it is not. Rather, it is a demonstration of my deep respect for the Senate and Senator Padilla's office, so that this issue does not cause further distraction or harm. To prevent this baseless issue from growing any further, I would rather remove myself from the spotlight and allow the Senate to focus on its important work." Bago ang kanyang pagbibitiw, hiniling kay Montenegro na mag-file ng leave of absence. Samantala, tingnan ang ilang celebrities na nadawit noon sa isyu ng droga:
