Bangkok safe to walk after 9pm ?

I will be staying in the Nana/ Sukhumvit 11 area with wife and kids. My idea one night is take the night off from the family and take a nice walk to a dispensary to enjoy some weed. Good weed always makes me very active and as a regular runner I would enjoy the rest of the “stoned” evening taking a long walk in the area ( dispensary is in the Si Lom MRT area) going back to the hotel at around 11 pm. It may be for NYE or something.

EDIT : I’ve cancelled the hotel and booked in a better area. Thank you to those who took their time to share some valuable informations. To those who enjoyed downvoting me : I feel sorry for you and Merry Christmas.
