Will poison work on Polearm Master feat's bonus action (second)attack when using a poisoned halberd?
Poison can be applied only to slashing or piercing weapons, but it's not applied directly to the opposite end of the weapon. So, will it work?
The Polearm Master feat (PHB, p. 168) says, in part:
When you take the Attack action and attack with only a glaive, halberd, quarterstaff or spear, you can use a bonus action to make a melee attack with the opposite end of the weapon. The weapon's damage die for this attack is a d4, and the attack deals bludgeoning damage. This attack uses the same ability modifier as the primary attack.
The description of the vial of basic poison says:
You can use the poison in this vial to coat one slashing or piercing weapon or up to three pieces of ammunition. Applying the poison takes an action. A creature hit by the poisoned weapon or ammunition must make a DC 10 Constitution saving throw or take 1d4 poison damage. Once applied, the poison retains potency for 1 minute before drying.
Will the second attack, if successful, apply the poison to the intended target?
