The Customs department at Mundra port in Gujarat`s Kutch district seized 68 lakh Tramadol tablets worth Rs 110 crore from two export containers destined for the West African countries of Sierra Leone and Niger, reported news agency PTI.

Tramadol has gained notoriety in recent times as the `fighter drug` after it was reported that ISIS fighters consume it to stay awake for long hours, said a PIB release on Monday.
