Hi, please stop smoking
as smoke is a big irritant and can lead to edema of the throat mucosa or food pipe opening and can lead to difficulty in swallowing.
Otherwise please use proton pump
inhibitor, syp. mucain gel and avoid spicy and oily foods. Use of substances which are of abuse can lead to many problems and the one faced by you is one of those many.
In case your dysphagia does not recover, please consult an ENT/gastro and you may need a flexible upper GI endoscopy
